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
