Change default colors for people with red green blindness

[hprid]

People with red green blindness can't distinguish the default colors for "yes" (99cc66) and "no" (ff9966). This affects about 5% of the people (with men more often affected than women).

I met a guy with red green blindness and we agreed on the following colors, which can be distinguished:
Red (no): c43131
Green (yes): 90db46
Yellow (maybe): ffe800

While I understand the suggestion and would like to make sure we find a good solution, I think these high contrast colors look too massive...

I could imagine a high-contrast mode to be toggleable and automatically generated from the color scheme (just crank up the contrast programmatically). I would also rewrite how background colors are assigned to the cells in the same step.

I think it's better to support people with disabilities without having them to enable some special mode. You could try the following colors, which are less "massive" but still distinguishable:

No: ff884d
Yes: ace673
Maybe: ffff66

I realize this might be a matter of taste, but even without having red-green-blindness, I prefer the first set of high-contrast colors @hprid proposed to the current default (and to his second suggestion). To me, the strong contrast emphasizes the pattern of choices and makes it easier to get a feeling for the vote distribution at a quick glance. Since this is the primary information a Dudel poll conveys, I think it is a good idea to highlight it.
