These are the colors (Testors) which I've found most closely match the pictures (boxes, Osprey books, etc.). For one shade colors, here are the Testors numbers; black (1149 or 1749), white (1168 or 1768), gold (1144 or 1744), silver (1146), steel (1180 or 1780), brass (1182 or 1782), flesh (flat-various available shades or mixtures). Testors is sold in Europe under the name "Model Master".
NOTE: colors based on the Osprey books- Men At Arms series #69,Elite series #7B,Warrior series #27, and the box art.
ALL COLOR NUMBERS ARE TESTORS UNLESS OTHERWISE STATED.
NOTE: Except for the popular reds, tunic and crest colors are pretty much optional.
White is the most common cuirass color but others also seem to have existed.
