Try it out. Post results here. (0-99, where 0 is best and 99 is worst)
Edit: I should warn you though that it's pretty mindnumbing.
edit: Could have probably done better, but got tired and just pressed the score button. Got an 8. Errors mostly with blue.

I think it helps if you arrange the similar colors first, then distance yourself from monitor to get the "bigger picture".
36 ... most of the hues close to one another I just grouped my problem seems to be with subtle differences with alike hues XP.
i got a 0 on my first try
Got 25, but I did it in a hurry because my eyes couldn't stand it. I guess it also helps what quality and type of monitor you are using.
tried it again with a brighter monitor; i got 12
/o/
\o\
I got a zero as well. Laptop, while charger is plugged in (hence a brighter screen).
I didn't bother to take that test, as i've known for a long time already that i definitely am color-blind. I can see colors just fine but i have a real hard time differentiating shades and gradients, especially among the cooler colors like blue, violet, purple and green. Feth that Ishihara guy.
I'm sure that if i even took the test, i'd get the lowest score.
Got 4. Good enough for me XD
Got 8. I do this when I arrange my coloured pencils by hue and I was correct about myself having troubles with greenish blues/bluish greens.
I was too stressed to begin with, and got this.
