This is probably a silly question but i was wondering if anyone could tell me how colour blindness effects the ability to match colours, i am currently a trainee graphic artist and am occasionally required to take the colour of a logo and match it with a chart of colours for print, there has been atleast one occasion when i have gotten my boss to look at the colour i matched and he has just said "nah nowhere near it"-It could just be because i'm bad at colour matching but i wanted to know whether it might be my colour blindness making it difficult.As far as i know i have Red Green Colour blindness & i don't think it's severe but cant be sure. Any help would be appreciated, Thankyou
