Maybe the best thing to do is to ask the blind person how he/she would like a color to be described, or try using various senses like touch, temperature, sound, and see which one the person can relate to best.
I would rely on his/her sense of touch. Using a fabric that has a somewhat rough texture, I would explain that the color red is like this...rougher than most colors...orange could be describes as similar to red. I would use silk to describe white since it is soft and silky, easy to look at. Blue could be a piece of ice...sometimes cold and unfriendly. "Sky-blue" is softer because it has some 'silky' white mixed into it. For yellow, I would warm something slightly...maybe a muffin and have them smell it and hold it close...yellow is warm an inviting, like the sun! Use a blanket to describe green because it covers the earth and trees like a thick blanket...just as white (snow) blankets the earth and trees in the winter. The imagination is a wonderful thing. :)
