CSS system colors don't match (macOS) system accent color preference For example, i have "Graphite" as my accent color in macOS, therefor when selecting text i expect the highlight color to be grey. However, when i'm using CSS "highlight" color as background color, the highlight color is always blue, regardless of my OS preference The example is demonstrated here: https://jsfiddle.net/1hx69ud7/
This appears to be intentional to reduce fingerprinting, see bug 188203.
ah ok, thanks!
