I well remember colour blindness being discussed at mapping clinics in NZ around 15 years ago! About the time when purple ball point pens first became available.   Phronimos Posted: 23 February 2012, 2:11 AM   It's a great sport, but I feel somewhat disadvantaged not being able to determine the runability of a map, and can not distinguish the contour lines against certain runability shading. Now we've only got to change the control flags to blue/white instead of orange/white and all will be good.   robbie Posted: 23 February 2012, 12:40 PM   When I started orienteering 1000 years ago we had a blue vertical strip in the outside of the flag. I dont know why it was dropped.   Michael Posted: 23 February 2012, 1:04 PM   Ahh, so that's why the tracks on tonight's map had blue innards. I thought it was just warning us that they were slippery due to recent rain..
