[Octave-bug-tracker] [bug #47911] sombrero in gnuplot ignores colormap

[Dan Sebald]

Follow-up Comment #15, bug #47911 (project octave):

OK, I'm getting familiar with this again.  If I recall correctly, that
original bug that motivated the color change was about face color (and black
surface plots).  Hence the hunk of code Ben pointed out


1181                 ## Convert color to 24-bit RGB
1182                 zz(:,kk+3) = hex2dec (sprintf ("%02x%02x%02x",
1183                                                round
(255*obj.facecolor)));


Apparently what is happening is the characters of the string "flat" are being
treated as numerical RGB values and it somehow gets interpreted as bronze.

I'm attaching a patch that solves the immediate issue of the sombrero. 
There's a lot going on here with so many figure properties.  There are bound
to be more small tweaks like this one still needed for the code.
