I think my green vision is deficient, but have been able to do commercial photography, electronics, and electrical work for 50 years. The use of a red filter lightens reds and darkens greens, so that red contact in one eye with a wink to double check, or moving a red filter in and out of the path of vision works just fine. Putting names on colors is still tricky though. In my case, only a few shades of red or green will be confused.

And it’s very simple to take too. You just have to try to match the two colors you see in the boxes below. The left box has hues that can be changed by the slider below it. If you get a match, press Match OK and if you can’t match them use the No Match possible! button. Easy, isn’t it? You could take it here.

Actually, there is no way to duplicate the various color tests, because the various color tests use monochromatic pigments. The computer monitors mix thee primary colors Red, Blue, Green. This is interesting, because there are many web sites that claim to have color tests that test color defects by mixing colors that "look" like the real color tests. The RGB anomaloscope above is on the right track. Sharp has come out with a four color RYGB monitor that should work much better. The yellow alone or mixed, might be matchable with a different combination of thee or four colors.
