OddContrast is a color format converter,
featuring newer color formats like
Oklch, Oklab, and the Display P3 color space.
It’s also a color contrast checker
to help designers meet
WCAG 2 accessibility standards.
In additional to Oklch, Oklab, and P3, OddContrast also includes hex, HSL, Lab,
LCH, and sRGB. Enter a color from the available color formats and convert it to
any other supported format. OddContrast provides an alert if the color you
entered is out of gamut for a given color space. Adjust the sliders until your
desired color is back in gamut.
OddContrast checks the contrast ratio between two colors and displays pass or
fail information based on the WCAG 2 accessibility standards for AA and AAA in
normal and large font sizes. If you need a reminder of the contrast ratio
requirements or what font size qualifies as large, OddContrast provides helpful
tips and a link to learn more.
OddContrast is still in development. Let us know if you have a
