Reading further I realized that in LCH the luminance is defined to be in [0,100],
so I screwed this up :/
Comparing again Colors.distinguishable_colors(8)
with Color.distinguishable_colors(8)
made me wonder though why yellow is skipped in favour of a third blue (I don't find 5 and 8 so easy to distinguish :/) in the new version...
Well, it's not broken so feel free to close this.
from colors.jl.
Oh, would we maybe have some space for fixed color palettes like these?
from colors.jl.
The difference between the old and new is that it performs the computations in LCHab space in the new one; it constantly converts between RGB and LCHab in the old one. There could, of course, be a bug; you could @show
the color differences between candidates you like and the ones it chooses, if you feel like diving into this.
from colors.jl.
I'd be fine with having some fixed palettes. There's a ColorBrewer package already, interestingly. Not really my expertise, so others should chime in.
from colors.jl.
Correct me if I'm wrong, but increasing the desired number of colors just adds new colors to the palette and doesn't change the already obtained. I wonder if it possible to obtain the really maximally distinguishable colors this way. Shouldn't I have to move all colors when adding a new one?
The simple picture in my head is that of a circle. When choosing n points with maximal distance I divide it into equally large sectors, but this requires changing multiple points when increasing n.
from colors.jl.
Correct. This package produces the nth distinguishable color as the one "farthest" from the first n-1. It does not reconsider the first n-1 in light of the chosen value for the nth.
Another algorithm would, of course, make a fine contribution. Would be interesting to compare performance.
