The browns and blacks, like the blues, yellows, and reds, are simply used to express local color.

They are employed for hair, eyes, eye-brows, and sometimes for bows and sandals.

The other colors are applied as follows: yellow is used for flesh, for shafts of weapons, for horse trappings, sometimes for horses, for chariots, cups, earrings bracelets, fringes, for wing-feathers, occasionally for helmets, and almost always for the hoofs of horses; blue is used for shields, for horses, for some parts of horse-trappings, armor, and dresses, for fish, and for feathers; white is employed for the inner part of the eye, for the linen shirts worn by men, for the marking on fish and feathers, for horses, for buildings, for patterns on dresses, for rams' heads, and for portions of the tiara of the king.
Olive-green seems to occur only as a ground; red only in some parts of the royal tiara, orange and lilac only in the wings of winged monsters.
It is doubtful how far we may trust the colors on the bricks as accurately or approximately resembling the real local hues.

In some cases the intention evidently is to be true to nature, as in the eyes and hair of men, in the representations of flesh, fish, shields, bows, buildings, etc.

The yellow of horses may represent cream-color, and the blue may stand for gray, as distinct from white, which seems to have been correctly rendered.
