Yes! This would be perfect to use with my #730 contrast function, which does indeed use lightness for this exact purpose. Edit: I did't see your code attached, duh, sorry. |

Deciding whether to use white/black text on top of a given background color is much better decided using the backgrounds "luma" rather than "lightness". Luma is a better measure of the intensity of the light, since it differentiates between colors that we do not see as well (30% red, 59% green, 11% blue).
