Frequently Asked Questions

What are complementary colors and why are they important?

Complementary colors are pairs of colors that sit opposite each other on the color wheel. When placed side by side, they create maximum contrast and visual impact. They're important in design because they can make elements stand out, create balance, and guide the viewer's attention. However, they should be used carefully as their high contrast can be overwhelming if overused.

How is a complementary color calculated?

In RGB color space, a complementary color is calculated by subtracting each RGB component from 255 (the maximum value). For example, if a color has RGB values (150, 50, 200), its complement would be (105, 205, 55). This mathematical relationship ensures that the colors are opposite each other in the color spectrum.

When should I use complementary colors in my design?

Use complementary colors when you want to create strong visual contrast or emphasis. They're effective for call-to-action buttons, highlighting important information, or creating vibrant designs. However, avoid using them for text-on-background combinations as the high contrast can cause eye strain. Instead, use them in smaller doses or adjust their saturation and brightness for better readability.
