Frequently Asked Questions
Complementary colors are pairs of colors which, when combined, cancel each other out by producing a grayscale color like white or black. On a color wheel, they sit directly opposite each other.
They provide the strongest visual contrast possible. This makes them perfect for call-to-action buttons (CTAs), highlights, or any element you want to stand out against a background.
Mathematically, the complement is found by subtracting each RGB value from 255. For example, the complement of pure Red (255, 0, 0) is Cyan (0, 255, 255).
