A guide to using new color spaces & formats with OddContrast
OddBird’s color tool not only checks contrast ratios, but supports the new CSS color formats and spaces.
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.
