What Is Split Complementary Color?

The split complementary color scheme is a creative and versatile color combination that draws upon the principles of complementary colors but with a slight variation. While traditional complementary colors are directly opposite each other on the color wheel, split complementary schemes involve taking one base color and pairing it with the two colors adjacent to its complementary color. This creates a triadic color scheme with more complexity and visual interest while maintaining balance and harmony.For instance, instead of using red and green (a complementary pair), you would select red as your base color, and the split complementary colors would be yellow-green and blue-green. This combination offers a wider range of contrast than analogous or monochromatic color schemes but avoids the intensity of a direct complementary pair, making it more flexible and adaptable to various design contexts.A split complementary color scheme is particularly effective because it allows for contrast and visual interest without the harshness of direct complementary colors. It is often used in design and art to create a balanced, yet dynamic, visual effect that draws the eye in a more subtle way than high-contrast complementary color schemes.

How to Find Split Complementary Colors?

Finding split complementary colors is a straightforward process once you understand how the color wheel works. Here’s a step-by-step guide on how to do it:

1. Start with a base color: Begin by selecting a primary, secondary, or tertiary color that will serve as the foundation of your palette. This will be the dominant color in your design.
2. Identify the complementary color: On the color wheel, find the color that is directly opposite your base color. For example, if your base color is blue, the complementary color will be orange.
3. Select adjacent colors: Instead of using the direct complementary color, look to the two colors immediately adjacent to the complement. In the case of blue, the colors adjacent to orange are red-orange and yellow-orange. These two colors, along with the base color blue, form the split complementary color scheme.

If you’re unsure about your choices, various digital tools like Adobe Color, Coolors, or Paletton offer easy-to-use interfaces for generating split complementary color schemes. Simply input your base color, and the tool will automatically generate its split complementary counterparts. Split complementary schemes are ideal for creating vibrant, harmonious designs because they offer contrast without the high tension of direct complementary colors. This makes them particularly useful in web design, branding, and advertising, where you need to capture attention but still want a balanced, pleasing aesthetic.

How to Use Split Complementary Color Scheme in UX Design?

Using split complementary color schemes in UX design can bring a lot of depth and sophistication to your interface while maintaining readability and user-friendliness. Here’s how you can effectively implement this color scheme in your UX designs:

1. Select a Dominant Color: Your base color should dominate most of your design. This color can be used for large background areas or the primary UI components. It serves as the foundation of your design, helping to create visual consistency. For instance, if you choose blue as your base color, it could be used in the navigation bar or header section.
2. Use Split Complements as Accents: The two split complementary colors should be used more sparingly to highlight important elements in your design, such as buttons, links, or call-to-action sections. These accent colors help guide the user’s attention to key areas without overwhelming the overall design. For example, if you have blue as your base color, red-orange could be used for action buttons, and yellow-orange might be employed for subtle highlights or notifications.
3. Create Contrast Without Overwhelming: One of the biggest advantages of the split complementary scheme is its ability to create contrast without being jarring. In UX design, this is essential because you want to draw attention to certain elements without sacrificing usability. Too much contrast between background and text, for example, can lead to eye strain, so it's important to use this scheme judiciously.
4. Consider Accessibility: When using a split complementary color scheme, make sure that there’s enough contrast between the colors, especially for important elements like text and background. Use tools like the WebAIM contrast checker to ensure that your colors meet accessibility guidelines (WCAG), making your site usable for all users, including those with visual impairments.
5. Balance the Design: While the scheme offers rich contrast, be mindful of how you distribute the colors. Use the base color as the dominant hue, the second split complementary color for secondary elements, and the third as subtle highlights or hover effects. This balance helps maintain visual harmony without overwhelming users.

In UX design, split complementary schemes can add a sense of vibrancy and attention to detail without distracting users from the overall functionality of the app or website. By keeping the balance between colors and using them strategically, you can create a design that is both visually appealing and user-friendly.
