Since we use ColorDiff already, just use its XYZ colorspace conversion code to get the value. * Require at least 3:1 contrast for both accent and foreground colors * Lower required contrast for the accent color	2020-10-19 15:40:14 +02:00

Fix thumbnail color extraction (#14464 )

* Fix contrast calculation for thumbnail color extraction

Luminance calculation was using 0-255 RGB values instead of 0-1 sRGB values,
leading to incorrectly-computed contrast values.

Since we use ColorDiff already, just use its XYZ colorspace conversion code
to get the value.

* Require at least 3:1 contrast for both accent and foreground colors

* Lower required contrast for the accent color
