Generate distinctly different RGB colors in graphs

Question

When generating graphs and showing different sets of data it usually a good idea to difference the sets by color. So one line is red and the next is green and so on. The pro

Answer 1

I would start with a set brightness 100% and go around primary colors first:

FF0000, 00FF00, 0000FF

then the combinations

FFFF00, FF00FF, 00FFFF

next for example halve the brightness and do same round. There's not too many really clearly distinct colors, after these I would start to vary the line width and do dotted/dashed lines etc.
