Improving colors for color blind people (issue lichess-org/lila#10410)

[Rabergsel]

Issue lichess-org/lila#10410 : Colorblind people cant see the difference between red and green.

Making higher contrast in color brushes so colorblind people can at least see different shades of red and green, and deuteronopia people (blue-green) now should see different shades too, because of making contrast of green and blue higher.

I didn't change the colors in total, I only varied them to make the contrast higher (and for me they still look good).

Could you post a screenshot of how it looks?

Also, you can link to an issue from another repo using lichess-org/lila#10410

And ideally, the PR title should still independently explain what your doing (not just "fix issue 13234") and same goes for the commit title ("update state.ts").

I added a normal vision representation and a protanopia (red-green colorblindesss) filter simulation of the analysis board.

Maybe it should be mentioned that the colours were chosen by color replacing.
