@anathem @ctietze @kate For me there are 4 that all might as well be the same colour. The first one is whiter, but the next 3 are all the same.

@ksaj @anathem @kate I don't even know which the "cyans" are; I guess the 4 rightmost colors?

The middle 2 of band is a bit "meh" for me, kinda works even when I squint.

Interesting to see the kinds of trouble you two have!

@ctietze @ksaj @kate "My" two cyans are the 4th and 5th color from right (or the two rightmost in your excerpt).

Wait... my definition of cyan always was "blue-green with a bit of whitestep", as if cyan never occurs without a bit of white mixed in.
But now I think about deuteranopian response curves (i.e. the green response is shifted towards red), which suggest that this whitestep is in my perception only (red would respond almost like green on cyan).

@anathem @ctietze @kate Here's one of the best spectrum comparisons I've found. I have tritanomaly.

@ksaj I do suspect that this chart would only make sense to normal-sighted people. I do see a difference between Baseline and Deuteranomaly, it's the smallest difference out of all lines, but I do suspect that difference is due to the fact that I'm seeing it on an RGB Monitor made for normal-sighted people.
I'd need that chart emitting real wavelengths instead of RGB mixtures, I'd think.

@anathem Yea, they aren't perfect. But it's pretty close-yet-not-perfect for me for the tritanomaly spectrum.

@ctietze @anathem @kate I can only tell what part this is because of the first grey line. It looks like a gradient chart.
