Since there are a variety of color-blindness conditions, it is difficult to give comprehensive advice.sillyrobot and icarlc Any suggestions moving foward to help you guys with that? Would highlighting them but also making thing brighter or dark help?
The most common is red-green deficiency which is what I suffer from. Reds tend to be dimmer than you'd expect. So deep red and dark purple might be the same, for example. Reds and greens "bleed" into gray and gray can be seen as either depending on surrounding colour and brightness. So shifting towards gray may not be very noticeable.
The easiest way to make the highlights more visible would be to alter the brightness level as opposed to the hue. If you do want to adjust hue, I'd suggest altering both red and blue at the same time.
Here's a link to a sample that shows what typical color-blind people see compared to a typical person. The protanopia picture and the typical picture are almost indistinguishable for me though I can pick out a bit more orange in the typical image.
