Another solution if you do not want to create your own colors.

Octave has many colormaps defined (also you can get real2rgb package
from matlab exchange file) and you can use them to generate palettes
for your plots.
Example:
Let say you have N different datsets you want to plot, each one with a
line of a different color. Let say you have a vector t (kx1) and the
datasets in a matrix data (kxN).
You plot them

h = plot(t,data,"-")

Then you create and assign your palette

palette = jet (N);
for i =1:N
set(h(i),"color",palette(i,:))
end
