Improve color scheme for people with color vision deficiency

WT Something like 8-10% of males (in Northern Europe and US) have some form of color vision deficiency (https://en.wikipedia.org/wiki/Color_blindness). Red-green issues are the most common (
https://en.wikipedia.org/wiki/Color_blindness#Red.E2.80.93green_color_blindness).
I'm one of them and it's not easy for me to discern the little red/green rings that are used to show moves when looking at problem solutions on the phone screen. It's not so bad on a monitor.

It would probably take a little experimentation to see what would work best. Solid dots come to mind or a different color/brightness/hue for the board?

Just something else to think about and maybe add to your list :) I know content has priority (it should).

Darrell Malick Yeah, those little rings are a bit hard to see anyway. I'll experiment with them when I get a chance and see how it can be improved.

cook777 I'm 100% color blind. I don't seem to have issues telling the difference between the two, but the green seems to blend right into the board. It would be nice to not have that issue. It was more annoying at first because I couldn't get any right answers. (I now know to hit reset and look for the ? mark in the center of the board when that happens.) it's not a big issue for me but something to keep in mind when working on this.

Making things harder is color blindness effects people differently. Maybe making things more customizable. For example being able to change the colors. No idea how much work that is, so a simple change to something better then the little rings is good too.

Darrell Malick Hi cook and everyone.

I agree - this needs to be better. I have added it to my to-do list with a high priority. However, we are in the middle of another package of changes and I don't want to let anything conflict with getting that package online because it fixes a whole bunch of problems, small and large.

So, as soon as that is online, I'll work on making the board marking more visible. In the meantime, I'm sorry and appreciate your patience.

cook777 No rush. For me it's not a big issue. I was just adding to the conversation for when you can get to it.

Very true. So maybe use shape in addition to color, e.g., little red x's instead of red rings or add a red x inside the red rings.

Darrell Malick Red and green should be easier to see on the problems goban now. I haven't gotten to the discussion page yet.

WT A little better, but still hard. Shape in addition to color would be the best. Like you do when you indicate in a problem where not to play or where to play with the x and circle.

Found another colorblind "issue": the 56 in the Days in a Row box is displayed in a way that is use to test for colorblindness :)
