Color Wheel Position
A complementary color finder helps designers and developers instantly discover the color sitting directly opposite on the color wheel — 180 degrees away in hue. Complementary colors create maximum contrast and visual vibration when paired together, making them a cornerstone of color theory used in logo design, UI color schemes, and artwork. Enter any HEX code to get the complementary color in HEX, RGB, and HSL formats.
A complementary color is the color directly opposite your chosen color on the color wheel, shifted exactly 180 degrees in hue. For example, red's complement is cyan, yellow's complement is blue, and blue's complement is orange. These pairs create maximum contrast and visual tension.
The input HEX color is converted to HSL (Hue, Saturation, Lightness). The hue value is then shifted by 180 degrees — wrapping around at 360. The saturation and lightness stay the same, so the complement shares the same brightness and vividness as the original color.
Complementary color pairs are used to create high-contrast accents, call-to-action buttons, and visual balance. They make elements pop without clashing. Common uses include brand color schemes, data visualization highlights, and artwork where you want two colors to strongly stand out against each other.
The tool outputs the complementary color in three formats: HEX (e.g. #FF6B00), RGB (e.g. rgb(255, 107, 0)), and HSL (e.g. hsl(25, 100%, 50%)). Each value has a one-click copy button. The same three formats are also shown for the original color.
