So I’ve been digging on the blue, gold (yellow) and white color symbolisms in different ancient cultures and they all seem to loosely correlate. Basically Blue represents water, sky, and in some references, the “great flood” which is all basically symbolic of purity or purification. White is again a symbol of purity and also peace/tranquility. Gold (yellow) basically symbolizes eternal, indestructible, powerful, etc. (maybe because of the properties of gold itself?) but anyways, I have no solid way to connect this to all the weird temples. My gut feeling is just simply that these people view themselves as basically living gods, hence the “stupidity” or what I would define as arrogance. Basically “Who’s gonna fuck with us?” Attitude. So the colors would symbolize maybe that they would remain all powerful (gold dome on TOP of freaky temple places) through the (blue) great flood and (white) purification of the planet, or us as a species. Or even that they would bring it about, wtf idk. I’m basically blabbing about shit we all probably already think but that’s just the gut feeling I have about their symbolism.
