Complementary Color Generator
Pick any base color to instantly find its complement — the color sitting exactly opposite on the color wheel. Complementary pairs produce maximum contrast and are ideal for bold, high-impact designs.
What Are Complementary Colors?
Complementary colors are any two colors that are directly opposite each other on the color wheel — exactly 180° apart in hue. Classic examples include red & green, blue & orange, and yellow & violet.
Because they're maximally separated on the wheel, complementary pairs create strong visual contrast. When placed side by side they make each other appear more vivid; that vibration effect is called simultaneous contrast.
Common uses include call-to-action buttons on a colored background, sports team color schemes, product packaging, and any design that needs to stand out quickly.

When to Use Complementary Colors
- Call-to-action buttons — an orange button on a blue page is impossible to miss
- Data visualization — comparing two quantities where contrast clarifies meaning
- Branding & logos — high-visibility combinations like blue & orange or red & green
- Photography & art — complementary backgrounds make subjects pop
- Interior design — using small accents of the complement to energize a neutral room
Tip: to avoid a jarring effect, use one color as the dominant tone (about 70%) and the complement as an accent (30%). If you need a softer version of this scheme, try the split complementary generator instead.

- Analogous Colors — neighboring hues for calm, cohesive palettes
- Triadic Colors — three evenly spaced hues for vibrant, balanced palettes
- Tetradic Colors — four hues (two complementary pairs) for rich variety
- Split Complementary Colors — a softer alternative to the strict two-color complement
