A test kit for the color blind?

[JohnT]

I'm scrounging thru craft stores like AC Moore and Michaels' trying to find a red tinted cellophane that will suit me. Some work better than others but nothing is "right"... yet. When the filter is right, all green is like golf course grass, red is like a firetruck and brown is unmistakably brown. No pale tints, etc.

Try a photographers supply place. "Gels" are used to filter light and come in a wide variety of colors. Rosco is one company to try.
