Hi Tom,

I agree but I have not come across a pair of colours that widely imply stop/go, bad/good, reject/accept, ... conceptually and that are visible to those with red-green colour blindness.Any suggestions?

Hi Tom,

here is a good summary from the UX perspective:

https://uxplanet.org/using-red-and-green-in-ui-design-66b39e13de91?gi=4879d577a25a

perhaps the most useful information I can take from that is maybe using just one colour for the OK button is a better approach and make that green. Then at least those with red-green colour blindness can learn that the brown looking button is the OK button. Like this:
