Colors
Générateur de couleurs à fort contraste
Used by developers, writers, and creators worldwide.
A high-contrast color generator produces a text and background pair pushed to near-maximum contrast for situations where readability is the absolute priority. From a tint hue it builds an almost-black background and an almost-white text, each carrying just a faint trace of the hue so the pair feels designed rather than starkly clinical, then reports the real WCAG contrast ratio and rating. Pairs like these routinely exceed the AAA 7:1 threshold and suit high-contrast accessibility modes, outdoor or sunlight-readable screens, low-vision interfaces, and critical text such as warnings and legal copy. The relative luminance and contrast math run inline using the official WCAG formula, so the reported ratio is accurate, not estimated. Designers and developers use it to build a dedicated high-contrast theme, satisfy low-vision requirements, or pick the safest possible text pairing. Each value is a labelled, paste-ready hex code alongside its measured ratio.

FAQ
how high is the contrast
The near-black and near-white pair typically lands far above the AAA 7:1 threshold, often close to the 21:1 theoretical maximum of pure black on white, while the faint hue tint keeps it from feeling clinical.
why tint the colors at all
A trace of hue in the dark and light tones ties the pair to your brand and softens the harshness of pure black on pure white, without meaningfully lowering the contrast ratio that drives readability.
when should i use high contrast
Use it for accessibility high-contrast modes, outdoor or low-light screens, low-vision audiences, and critical text. For general UI, a comfortable AA pairing is often easier on the eyes for long reading.
