"In deciding upon a proper color, neither the zodiacal nor the planetary values should be considered separately but blended as an artist mixes paints upon his palette." - Manly P. Hall

There are many theories as to which color is associated with each segment of the zodiac. While there does seem to be some sort of consensus among experts, and non-experts alike, large discrepancies still exsist , even in the COLOURlovers library.

Today we are going to look at three theories. Two put together from historical references from Manly P. Hall and Finnish astrologer Juhani Nummela, and a newer theory proposed over at astrologyweekly.com. Plus, we'll see what people in the COLOURlovers community think their colors are.

Colors associated with the 360 degrees of zodiac

The visible part of spectre of electromagnetic waves is what we call light. More exactly, from the entire range of electromagnetic radiations, the human eye can only perceive those with the wavelength between 380 and 780 nanometers (nm). Below 380 nm, there is the ultraviolet radiation, beyond 780 nm there is the infrared range.

I think there is a correlation between the visible light of different wavelenghts and the zodiac: the visible spectre begins with red and ends with violet, this can be associated with the range of 360 degrees of the zodiac, from Aries to Pisces.

Since the light with a wavelenght of 780 nm is a red light, and the light with a wavelenght of 380 nm is a violet light, a correlation can be considered between the light of 780 nm and 0 degrees Aries and so on, ending with a correlation between the light of 380 nm and 29 degrees Pisces.
