ThibG 0ebc8d8626 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		2020-08-02 18:47:44 +02:00
