Re: [matplotlib-devel] release strategy and the color revolution

[Benjamin R. <ben...@ou...>]

Interesting choices, and I think we are on the right paths (no pun
intended) through the two possible colors. However, I think the same
problem arises that I noted before. Both ends of the colormap are nearly
black to nearly white. IIRC, our perception of luminosity has a much
greater range than it does for chroma. While it is nice to take advantage
of that, I wonder if we are going too far in the luminosity range? Perhaps
these colormaps would be better if the luminosity range wasn't as full as
it is here?
