All authorities, though variously, associate the colors of the spectrum with specific planets. In fact there are almost as many versions as there are authorities. Nevertheless the following planetary associations represent a consensus of opinion:
Sun: Orange, gold, deep yellows.
Moon: White, pearl, opal, light, pale blues; iridescent and silvery hues.
Mercury: Insofar as Mercury can be said to have any appropriate colors of its own, slate color, spotted mixtures. Most authorities agree that Mercury generally assumes the color of that planet with which it is in nearest aspect.
Venus: Sky-blue to pale green, lemon yellow; and tints in general as contrasted to colors.
Mars: Red, scarlet, carmine.
Jupiter: Royal purple, violet, some blends of red and indigo, deep blue.
Uranus: Streaked mixtures, checks and plaids like Joseph's coat "of many colors."
Neptune: Lavender, sea-green, mauve, smoke-blue and possibly peculiar shades of gray.
Pluto. Luminous pigments, in unusual shades containing a large percentage of red.
