colour blind designers?

Is colour blindness a problem in design? Colour blind is rare amongst females but is very common amongst males. Approximately 8% of all the men in the world have some form of colour blindness. Colour blindness is a bit of a misnomer of colour; most colour-blind people can see colour but confuse colours that so-called normal observers can easily distinguish between. The most common case is red-green colour blindness and such sufferers find it hard to tell reds and greens apart.

 

But does design take this into account sufficiently? One area where there may be a problem is in the gaming industry. I came across the following comment today where someone is reporting a problem using Call of Duty (a game I don;t play but which I understand is quite popular) on the Xbox. Apparently, the Gamertags of all the players are either green if they are on your team, or red if they are an enemy. Oops!! I wonder how much of a problem this is. The problem is probably greatest when colour is used to convey information (as in this case, friend or enemy) rather just for aesthetics (where the information may be conveyed by contrast alone).
