Thread Subject: colored markers in plot; cycling though colors

I'm adding points from different experiments to a plot and I would like to color them differently for each experiment. The problem is that the number of experiments varies. Therefore I need to make a color table that has n different colors, where n is the number of experiments. I realize that I can assign a color in a plot by using, e,.g:
plot( ...,'markerfacecolor',[a b c])

and my question is how do I vary a,b,c so that I get a (rainbow) spectrum of colors.

I tried:

for i=1:n
plot( [data from experiment], markerfacecolor',[1 1 1]/i)

and this resulted in shades of gray, which is difficult to view if there are more than 3-4 experiments.

Why not use the colormap?

T = colormap;
