I think your observations also apply to some extent to the Rider-Waite, which tends to defy color analysis. Frankie Albano tried to 'correct' this with P. F. Case's color symbolism, but this may have been somewhat ill conceived. Mary Greer is of the opinion that the Waite did not strictly follow the GD in many respects, and I am in agreement with this. Waite apparently was not happy with the GD ceremonial magic, and this reticence may have applied also to the GD color scales, which, to a large extent, were associated with GD ritualism.
Being, as always, the Fool (Le Mat), I am still interested in the magenta, yellow, cyan color scheme as it applies to the GD Tree of Life.
yeah, I do agree BUT ...
as an artist and magician ... and ESPECIALLY when one makes some GD stuff, it just doesnt work artistically, there are other things to consider as well, like saturation and tone ... some combinations although technically GD correct are garish and horrible. My own stuff I adjust the colours to make it aesthetic. Which Frieda nay have done.
Crowley once said, that after a while, you can walk into a temple and see what is wrong or out of balance at a glance. I dunno ... to make a whole temple that was in sync with these colours sometimes its just horrible. I have done it with painting magic squares with the 4 colur scales for each planet ... some are just horrible and dont work IMO.
Like a ritual , get the theory down, understand the why, then use artistic license.
