I have been thinking about implementing the handful of most important CATs a while ago, including the BFD (linear or non-linear), simple vonKries etc. As far as I remember CAT02...

The change to the progress message looks like this: ``` ... ... ... 01:20:14 | Time to finish: 0 d 0 h 1 min 28 s @ 1.064 MB/s average...

I found the following for the jet color LUT: http://cresspahl.blogspot.de/2012/03/expanded-control-of-octaves-colormap.html the r,g,b components of the jet LUT (256 color values) are defined by a simple scheme: ``` julia r,g,b=zeros(256),zeros(256),zeros(256) for...

If you do a quick sanity check of the color coordinates of A and B in the first example you can see that none of of the colors exist. They...

@dcjones Yes, alpha values don’t make much sense in terms of pure colorimetry because it would change the color coordinate depending on the background the color+alpha would be mixed with.

I’ll take a look at the papers on dichromasy that I have collected. Actually some dichromats see different color distances. For example they can be better at spotting camouflage than...

I guess that could be a good starting point. Maybe using even more sophisticated color spaces like the DIN versions etc. could lead to more regular palettes. I’m about to...

I found a rather new paper (from 2010) on color deficiency simulation. In contrast to Brettel et al’s algorithm (from 1997) it uses the physiologically based two-stage model of color...

I tried your difference matrix with the DIN99o color space instead and the range of difference is considerably smaller, between +10 and -50 instead of +20 and -80. The range...

@StefanKarpinski The paper @dcjones is talking about also contains a recolorization/color deficiency friendly palette algorithm. I find the daltonize algorithm from vischeck quite effective and I have the impression that...
