Invisible pink.

That's a rather interesting question :3.. my initial thought was green due to ties to nature, but I feel like green is too closely associated with islam like blue is withjudaism, so my other thoughts go to the main logo/symbol, which in it's primary depiction is this sort of orangy-yellowish brassy colour, which I do think could work, or the other option being the national colours of yellow, green and red, as it's a religion that's quite linked to the country, though of course 3 colours doesn't necessarily work for all situations, and also those 3 colours moreso invoke the idea of the modern country, so it may not be an overall best fit

fluorescent brown. wait, orange, no, plaid, no wait, what's the color for antitheism again guys, I deleted that memo.
