Complementary colors are the colors that sit opposite to each other on the color wheel. As the name suggests (complementary and not complimentary), these colors help each other stand out. They bring out the best in each other by making their complement more vibrant or noticeable. Complementary colors also work together to elevate the overall visual experience.
When you place complementary colors next to each other, they create high contrast and appear brighter. Alternatively, they cancel each other out when you combine or mix them. This means they lose intensity and produce a neutral color.
Color theory studies how colors work together and affect emotions and perceptions. It is a combination of art and science that determines what colors look good together.
In this video, Arielle Eckstut, the author of "What Is Color?” shares the idea that color is a product of our imagination. Our brains play a significant role to process visual information and inform us about the world.
To use colors effectively, designers must have a solid command of color theory and know the color wheel inside out.
There are two types of color wheels:
Based on the primary colors of RYB—Red, Yellow, and Blue. RYB are primary colors for subtractive (pigment-based) color theory. In subtractive color theory, mixing colors removes certain wavelengths of light and reflects others. A mixture of all primary colors results in a muddy brown, almost black color.
Based on RGB color—Red, Green, and Blue. RGB are primary colors for additive (light-based) color theory. In the additive color theory, primary colors combine to form new colors. A mixture of all the primary colors creates white light.
Color harmony refers to the relationship between colors. Designers use geometric relationships on the color wheel to create pleasing color combinations. You can use a color wheel to determine the relative positions of different colors. Additionally, you can find color combinations that create a pleasing effect. You must also know about different color schemes other than complementary.
Appropriate color combinations must be combined with sound design principles to guide user attention and enhance user experience. Ensure that your color choices follow the principles of unity, Gestalt, hierarchy, balance, contrast, scale, and dominance.
Think of complementary colors as "opposites attract." The classic examples of complementary color combinations are:
Red and green
Orange and blue
Yellow and purple
If you include the variants of these primary colors, red, green, and blue (RGB), you may get another three complementary color examples:
Blue-purple and yellow-orange
Red-purple and yellow-green
Red-orange and blue-green
Using the full 12-color wheel, we get six pairs of complementary colors that you can use to design pleasing experiences. These six color combinations can work wonders if you're designing a website or a digital presentation:
Red and cyan
Green and magenta
Blue and yellow
Orange and azure
Chartreuse green and violet
Spring green and rose
Typically, a pair of complementary colors comprises one warm color and one cool color. For example, yellow is a warm color, and purple is a cool color.
Visual perception plays an essential role in what we see. The perception of colors results from how our eyes and brain process different wavelengths of light. Color is a perception of energy and specific wavelengths of light that reach our eyes.
Arielle Eckstut explains the significance of color in our perception and how designers use it to convey information effectively.
Our eyes have three types of color receptors. These special cells, known as photoreceptors, respond to color in only three varieties: 'red,' 'green,' and 'blue.' To simplify, here's an exercise to help you learn how complementary colors work in visual perception.
Look at a green light for a while. After 30 seconds, suddenly turn to look at a white wall. You'll see a magenta light on the wall for a split second, which is green's complementary color. (Try it!)
When you look at a green light for a while, the green cells get tired, while the red and blue cells take a break. After 30 seconds, when you look at a white wall, the area with the tired green cells gets lit up by red, green, and blue light. The red and blue cells respond strongly, but the green cells respond weakly. Hence, we mostly see a mix of red and blue, creating a magenta color.
The above phenomenon is also called the afterimage phenomenon. It highlights the importance of color choices. Pleasing combinations attract attention and evoke positive emotions. Similarly, unpleasant combinations can put your users off. This shows how important it is to pick colors carefully. Pleasing color combinations can catch the viewer's eye and evoke certain emotions. Similarly, colors that don't go well together might not look good and could make people lose interest.
Complementary colors look great together because they make each other stand out and look balanced. They do this by stimulating different parts of our eyes equally. It's a natural illusion that adds energy and draws the eye. However, the nature of color is transitory. Our perceptions of color can shift under different lighting conditions. Joann Eckstut, a leading color consultant and interior designer, explains why colors change in this video.
Complementary colors are perfect to catch the viewer's attention. They can make a composition bolder, prouder, and more charismatic. There is no reason you should not utilize the power of complementary colors in UX design. However, nailing it requires a keen eye.
The key to using complementary colors well is to make one color more dominant.
There are several ways to do this. Let's see how you can use complementary colors in the design:
You can create shadows using a color's complementary color. It creates an interesting shadow instead of using black or gray. Complementary colors' gradient effects can add depth and visual interest to your design. This contributes to a more engaging and dynamic user experience.
For instance, let's say you have a weather app with a blue background representing the sky. You have a card that displays current weather conditions, like temperature and forecast. Instead of using a neutral gray, opt for an orange shadow to create a shadow for this card. This can enhance the realism and visual appeal of your app.
Use complementary colors to draw attention to essential elements. This can include alerts, notifications, or CTAs. Using complementary colors can make the information stand out. It ensures users notice critical details.
Take an example of the IxDF website layout. The orange CTA with the primary color blue is an excellent example of contrast in action.
You can apply complementary colors to different interface elements. The contrast between complementary colors makes certain elements stand out. Hence, you can use it for effective differentiation and emphasis. It helps your users understand the structure of your digital product.
An appropriate example is Agendrix—a staff scheduling and workforce management software. The dark teal color for the main background of their website gives a sense of calm professionalism. They also chose the perfect complementary shade of peach to emphasize key elements. Agendrix uses these two colors to distinguish calls to action to strategically guide users through the website.
Experiment with complementary colors for background and foreground elements. If the background is in one complementary color, the foreground elements (text or images) can be in its complement. This creates a striking visual effect.
Again, you must exercise caution. The contrast you aim to create must be enough to draw attention. At the same time, it should create a clear hierarchy while keeping the design balanced. Put simply, striking the right balance is key.
Complementary colors minimize eye fatigue. Hence, they're ideal for a website's navigation menu. Use complementary colors for dropdown menus, text, icons, and hover and active states. For instance, when users hover over or select a menu, the color changes to its complement. This switch gives users quick feedback, indicating the menu's interactive nature. It makes the website more fun and easier to use.
For example, A Short Journey is an interactive one-page website. It uses an orange and blue color website palette. This website uses different shades of orange for the background. This dominant color gives the website more depth. The foreground objects mainly use blue. This contrasting color lets visitors focus on the website’s interactable elements. This makes the navigation more intuitive and enjoyable.
Complementary colors in design can create visual interest, balance, and harmony. Here are some tips to make your complementary color combination stand out.
To create excellent combinations, you must understand the following:
Color wheel: A visual representation of colors arranged in a circular format.
Color modes: The different ways designers use colors in digital and print media. Common modes include RGB (Red, Green, Blue) for digital products and CMYK (Cyan, Magenta, Yellow, Black) for print.
Color symbolism: The symbolic meanings and different cultural associations of colors.
Color theory: The principles and guidelines that govern color combinations.
Knowing the fundamentals can help you create compelling and emotionally resonant designs.
Think about the mood or emotion you want to convey. Complementary colors can create a strong contrast even when you reduce their intensity. So, decide if you want a vibrant and energetic feel or a more subdued and balanced atmosphere.
Different color combinations resonate differently with various demographics. For instance, a red and green combination can signify the "holidays." But it can also represent energy and rejuvenation. Consider the cultural associations, preferences, and emotions your color combination seeks to elicit.
Choose one color as dominant and the other as an accent. This can help to create emphasis and guide the viewer's focus. The dominant color should align with your main message or theme.
In this video, Michał Malewicz, Creative Director and CEO at Hype4 emphasizes the importance of simplicity in color selection.
It is best to use complementary color pairs in specific areas or elements of a design. Instead of using the combination in every design element, identify certain elements critical to the design's message. Selective application ensures the contrast attracts users without overwhelming them.
You might be designing a website, an app, or marketing collateral. Making color choices accessible means the broadest possible audience can understand your design. It also makes it more likely that your products or services will comply with equality legislation. Use contrast-checking tools to ensure that text will be legible. You should also use usability testing to confirm your color combinations.

Yes, complementary colors can improve website accessibility. Using complementary colors is an important part of accessible web design. Designers can make text easier to read and see by using contrasting colors. Opposite colors on the color wheel create a strong contrast. The contrast makes it easier to tell text apart from the background. It also makes buttons stand out from other things, so the content is easier to see.
Complementary color schemes also make websites inclusive. They are a good choice for people with different visual abilities and help create a digital environment that includes everyone.
When using complementary colors in design, there are some common mistakes to avoid.
Using too many colors that go well together can tire out users and make the design less attractive.
Not having enough difference between the color of the text and the background can make it hard to read and affect how users feel about the design.
Ensure the colors used look the same on different devices, so everyone can see the design as intended.
Using both complementary colors equally might create a clash and make the design look too flashy.
To find complementary color schemes easily, one can use complementary color generators. These online tools simplify identifying colors opposite each other on the color wheel. Designers can find perfect color pairs by clicking on colors opposite the selected hue. Adding a complementary color generator to the toolkit makes the design process smoother. It helps one create visually appealing and harmonious color palettes. Designers can use this tool to create impactful designs.
Complementary colors, which are opposite each other on the color wheel, have distinct psychological effects:
Complementary pairs create visual harmony and balance. They engage viewers and provide a pleasing aesthetic experience.

This helps create a memorable brand image. Designers can use complementary colors to make the app aesthetically pleasing and easy to use.
Yes! Using complementary colors in designs can impact the text readability. It's best to aim for a harmonious balance between complementary colors. For example, deep green text against a light coral background is a good choice. However, text in a vivid green hue against a bright red background, or vice versa, may prove excessively vibrant, hampering readability.
Designers should prioritize readability by ensuring the contrast ratio between text and background meets accessibility standards. They can also improve readability by choosing clear, legible typography and adjusting font size and weight.
Yes, complementary colors work well in minimalist design. They add interest and depth without making it complicated. In minimalist design, every element is important. Complementary colors help important elements stand out. They create a focal point in a simple palette. Complementary colors look good in minimalist design because they don't overpower the composition.
To help people with color blindness, here are some adjustments to consider:
Increase the contrast and adjust the brightness so that the differences between colors are easier to see.
Use patterns or textures along with colors to convey information. This way, even people with color vision problems can still understand.
Clearly label things and use symbols to show meaning. This gives extra clues beyond just using color.
Pick complementary colors that have enough contrast. This makes them easier to see, even for people with color vision problems.
By using these strategies, designs become more inclusive and accessible for everyone.
