Colorblind people have a hard time distinguishing red/green answer highlight

Question

I am red/green colorblind and I find it difficult to distinguish between the red and green circles that denote unanswered and answered questions:

Does it make sense to use, for example, a darker green if only a few percent of the user base will be affected by the problem?

Answer 1

Thank you for bringing this to attention, I'd like to take this opportunity to suggest instead an alternative to the full circle solution (much like FEichinger has suggested):

.unanswered .mini-counts {
  color: #666!important;
  border: 5px solid #dd4814;
  width: 30px !important;
  height: 22px !important;
  line-height: 20px !important;
}

Or, you know, tweak the green color. Also, scatter brain, make the orange have a dots pattern? Similar to that found on the Ubuntu branding page

Answer 2

I gotta say, I never really considered it from that perspective. I mean, when you think about it, the whole "red and green as bad/good indicators" kinda doesn't make sense in that light in general. Buuuut ... I fully agree. That is likely to cause problems. And just changing the colours would probably create the same problem for the next set of colour-blind people.

Slightly enhanced suggestion

I doubt just changing the colours would be sufficient overall. Perhaps we could turn it from full-circle for unanswered to a thick border - to give a straight-forward visual feedback that is entirely independent from the colours?
