Yeah. Defining distinct is a product of deferring to a color space then when we say maximally distinct colors what we mean to say is colors which are as far from all the other colors as possible. But since the color space doesn’t change the answer isn’t going to change. And implementing something that better … Read more
The 100 ms threshold was established over 30 yrs ago. See: Card, S. K., Robertson, G. G., and Mackinlay, J. D. (1991). The information visualizer: An information workspace. Proc. ACM CHI’91 Conf.

The method could vary depending on your needs. Here are 3 ways to calculate Luminance: Luminance (standard for certain colour spaces): (0.2126*R + 0.7152*G + 0.0722*B) source Luminance (perceived option 1): (0.299*R + 0.587*G + 0.114*B) source Luminance (perceived option 2, slower to calculate): sqrt( 0.241*R^2 + 0.691*G^2 + 0.068*B^2 ) → sqrt( 0.299*R^2 + … Read more
