The colors created by Paul Tol at SRON are good for publication-quality figures:
- distinct for all people, including color-blind readers
- distinct from black and white
- distinct on screen and paper
- still match well together
ptc6 calls up to 6 RGB colors.
use ptc12 if more colors are needed (up to 12).
ptc6(n) % n is the number of distinct colors
(a light gray is added at n+1)
To visualize each scheme of color selected, add 'check' to the function:
ptc6(3, 'check') % displays the 3 colors on a figure
