color

Two questions and a comment:

Q1. For 'figure' I'm not seeing any effect
of edgecolor (on screen). Isn't this the
color of the border between the face (or
frame) and the figure (as determined by axes)?

Q2. Can line colors be set to arbitrary rgb colors using
matlab.plot? If so, what is the syntax?
If not, can this be a feature request?

Minor comment:
is the 'y' yellow needed for a Matlab match?
If not, it needs adjustment IMHO.

fwiw,
