"High Degree of Cantrast" Question...
« on: December 03, 2009, 06:20:42 pm »
It occurred to me today that any combination of green & red for uniforms/numbers/helmet covers may cause problems.  Extreme problems if someone is color blind.  Granted it's not a typical color combination (outside of the season into which we are now entering), but it is possible.

Here's the question.  Would any of you be likely to ask a team to NOT use a red/green combo on uniforms/numbers & helmet covers?  Would you base it solely on visible contrast in the general sense?  Would you make the request even if you yourself could easily differentiate the numbers from the background on the basis that someone else might not be able to read the numbers?  Or would you check with all referees/officials/stats before making the request?

red and green are "colour opponents" which means they provide maximum contrast*. however "colour blindness and afterimages typically come in opponent pairs (red-green, blue-yellow, and black-white). "**

my humble opinion: if I am head reffing the bout and I have problems seeing the star on the jammer cover I ask the team to provide an altertnative. I don't need to ask anyone to make this decision.
But I would listen if officials or team captains tell me they have problems with the colour scheme. Then I would check if the covers could be replaced by better visible ones.

Don't look at the game with rules-tinted glasses; look at the rules with game-tinted glasses!
