Trail maps and the color blind
One of our projects this summer is to construct trail-guide-posts that will have an aerial photograph of the immediate property with trails overlain. The aerial photograph is green (forests) which raises the question of what color the trails should be so that they jump out AND are visible to the color blind. Red really jumps out (to me) but that would mean nearly 7% of the population wouldn't be able to read the maps. After googling to find out what colors are "universally" visible on a green background (one of those needle-in-a-haystack-moment), Renee (UMBS staff) pointed out that yellow is the way to go. I also found out another staff member is color blind so I have someone to test these maps out on before printing.
