The Zodiac and Colour

So I was and still am looking for information on colour correspondences and astrological sun signs. I have found that very few sites agree on what colours correspond to which sun sign. One simple 'rule' I found, which made sense to me, was that to consider the earth, air, fire, and water correspondences of the signs and use colours that are associated with those elements. I also found this site and I really like the attributes it gave to the colours.

Here is a site with a VERY detailed colour correspondence chart, showing exact shades:
