Color changing under graphic inclusion with graphicx

[Paulo Ney de Souza]

Hi Herbet,

Yes, this does work. ....but it leaves me with more questions than before
....

1- \usepackage[RGB]{xcolor} -- Does that imply that everything in this
document has to be done in RGB???
That seems to be a pretty big restriction.

2-  Is the use of:

    \usepackage{xcolor}
    \definecolor{bgcolor}{RGB}{80,64,83}

not enough to specify that RGB is being used?

3- What does the second row of mages have that the first do not???
