Well, if background is black then they can be told apart easily.I'm always frustrated when in a talk someone says "And the red line is..." and I'm thinking "Which one is the red line? They all look black." If the line is really thick then I can see the color, but if it's a thin red line, it's a no go.
Argh! I hate thin lines!
They don't look anything like black to me but a one-pixel red line and a one-pixel green line I can't tell apart.
