Magic and Ritual

Hello again, buscador!

It's good that you are thinking about how the color assignments should look. There are several possibilities. It is certain that east is the cardinal direction of the element of  air, south is fire, west is water and north is earth. In the system we use in the BOEL, the color yellow (gold) is used in the east, because this corresponds to the color of the sun, which rises in the east. The air element is about clarity of mind, speed and lightness, which is well represented by yellow. It is also the case that consciousness, the Ruach in the Qabbalah is associated with Tiferet. There, the sun is associated as the central point of our solar system and a synomym of our individual self. I find this very coherent.
Blue is used in the west because water can be aptly described as bluish. Fire in the south is red, there is probably no incompatibility about that. Finally, in the north we use green, the color of nature and living earth.

In the chapter you describe, blue is used for air in the east, green in the west, and yellow/gold in the north. As far as I understand it, I can understand blue for air, but green for water, that would be rather water in which there are many algae and that is not really healthy. Yellow/gold for the north I don't really think is accurate either. Green fits very well in my opinion. If you want to take something like gold/yellow as an association for autumn, I think that falls short, because the autumn colors are very diverse.

I hope this helps.

Lightful greetings
Oholiab
