I recently discovered that the “check color contrast” feature in the Figma color palette window is not 100% accurate and rounds up the contrast value compared to the WebAim Contrast Checker. This is very concerning and potentially problematic when resolving passing contrast levels among brand colors and accessibility. Warning to designers: be sure to double check your contrast levels and don’t rely on Figma’s tool alone!

Contrast Finder fails at 4.49631
Figma passes at 4.5:1
Stark plugin passes at 4.5:1
