heraldic colors
This introduces an interesting subject. The heraldic colors (more properly called "tinctures") have French names, of course, since the heraldic system was developed under the Normans, who spoke Norman French, even in England. The tinctures are:
argent -- originally silver, represented on paper as white
or -- originally gold, represented on paper as yellow
sable -- black
gules -- red, either scarlet or crimson
azure -- blue, usually cerulean
vert -- green, usually a fairly deep green, not light green
These are the standard tinctures; also possible, but rare, were
tenne -- ="tawny", orange
murrey -- deep purple (the color of a mulberry)
Anything represented in its natural color was described (blazoned) as "proper".
