> In the [current draft](https://drafts.csswg.org/css-color-5/#colorcontrast), transparency is ignored when calculating contrast, because it was ignored in WCAG 2.1 as there were no non-opaque colors then. Notice that APCA does specify blending the text color onto the background color using the text alpha, then computing the L <sup>c</sup>contrast of the blended result against the (assumed fully opaque) background. Of course this is made easier because the APCA formula requires specifying which is text and which is background :) -- GitHub Notification of comment by svgeesus Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/7358#issuecomment-1287929467 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
