On: All RGB colors in one image

That kind of proves the point. How many of those rules of thumb are you going to have to formulate to express in RGB what's trivial to find in HSV?

[nitrogen → andrewflnr]

Unfortunately I've already formulated them after working so much with RGB in low-level graphics code, pre-hsv() CSS, and some image editing software.

Actually, that sounds kind of like a fun challenge game: name a color, then try to guess RGB values for that color.

[entropy_ → nitrogen]

I've gotten pretty good at doing the reverse operation(given an RGB value, guess the color) because I'm red-green colorblind and that's how I figure out what color something is :)

The converse game exists: http://yizzle.com/whatthehex/

Edit: Actually, so does the “guess the RGB given the colour” direction, but I don’t find it as fun: http://mallory.jemts.com
