I am red-green colour blind, and apparently colour-blindness affects nearly 10% of all males. It's usually not an issue, except for when trying to follow flags during races. Unfortunately, it seems the most common colour for race flag is red or orange, which to me blends rather well into the green grass its usually placed upon. Does anyone else suffer the same problem as me?
It came to light most recently at the Kendal Winter League race at Firbank, where all the flags were a dark orange/red colour. I was in 3rd for a lot of the race and 1st and 2nd were well off in front, out of sight, and it was only through luck that I managed to guess the right route most of the time. Last weekend I did the Whitestone KWL race and they had used a combination of yellow and orange/red flags, which was a massive improvement! Even though I struggled with the orange/red flags, I could mostly spot the yellow flags in the distance (often noticing a closer orange/red flag as I nearly stood on it...).
I guess what I'm getting at is that, for me, flagging a route with entirely yellow/white flags would be a big improvement. But I'm also aware that this might be a step down in how much the flags stand out for those that aren't colour blind (I don't know if that's so, I'm just guessing that orange/red is used for the reason that to most people it stands out more than anything else).
