Follow-up Comment #1, bug #52599 (project octave):

Try the attached patch.

The image you are seeing is range 0-63 for 8-bit image, which naturally comes
out darker.  I can't recall why I would have scaled the true-color data to the
range of the color map for Truecolor data.  gnuplot does have a means of
generating images through a color map (and I'm sure that's what was on my mind
at the time), but that's not pertinent to 3-component data.  In any case, I
don't see any adverse effects in "rundemos draw" with the attached patch.
