In this regard, and for the purposes of signage, etc. it would be helpful. I'm dealing with blue-green colorblindness right now due to a pretty bad (3+ NS) cataract in my only eye, and while I don't have problems looking at colors on, say, a computer monitor, I often stand in my closet asking myself "Is this shirt blue, or is it green?" My solution has been to own a lot of grey shirts.
