Re: [csswg-drafts] [css-ui-4] choosing background colors for accent-color for contrast (#6159)

I can get close to that other magic number, `lab(53.135% 0 0)` is `color(xyz 0.20412 0.2117 0.1747)` so reative luminance *0.2117*. 

I don't understand the comment about kGoogleGrey900, either

But is is certainly a better threshold than a relative luminance of 0.5.
