>> If you look in the online help, under "Plot", then under the "Color" property, there is a link to "string or RGB vector". That page contains a list of the shorthand color names like "r","b","g" and it also contains a table of all of the colors.
Also note (thanks, Katie!) that this table gives the index for a color along with its name; e.g., 'hot pink' (in the upper right corner) is index 58:
IDL> print, !color.hot_pink
255 105 180
IDL> print, !color.(58)
255 105 180
This could be handy for indexing colors in a series of plots.

Actually, if you want a lot of colors, you should probably use the COLOR property instead...
p = PLOT(x,y,'o',COLOR='Burlywood')
You can get the list of colors by doing:
print, tag_names(!color)
If you look in the online help, under "Plot", then under the "Color" property, there is a link to "string or RGB vector". That page contains a list of the shorthand color names like "r","b","g" and it also contains a table of all of the colors.
