Color Inverter (Invert Hex Color)

Inverting a color turns it into its photographic negative: each RGB channel becomes 255 minus its value, so white becomes black and orange becomes a blue-cyan. This tool inverts a whole list of colors at once and also offers a smarter "lightness only" inversion in OKLCH — dark becomes light but the hue stays the same — which is what you usually want when turning a light theme into a dark one.

How to use this tool

1. Paste your colors, one per line.
2. Read the plain inverse (255 − each channel) for each color.
3. Use the lightness-inverted column when you need dark-mode versions with the same hue.
4. Compare with the complementary color, and download the before/after chart.

Formula

inverse = (255 − R, 255 − G, 255 − B) · lightness inverse = OKLCH(1 − L, C, H)

The plain inverse flips both hue and lightness. The lightness inverse keeps hue and chroma and only mirrors perceived lightness; chroma is reduced if the result would leave the sRGB gamut. The complementary color (HSL hue + 180°) flips the hue but keeps the lightness.

Example

Tomato #FF6347 = rgb(255, 99, 71) inverts to rgb(0, 156, 184) = #009CB8, a teal. Its lightness inverse keeps the red hue and becomes the dark red #640000, while its complement is the light cyan #47E3FF. Mid-gray #808080 inverts to #7F7F7F — almost unchanged — but its OKLCH lightness 60% flips to 40%, giving #484848.
