I believe God comes in many colors. Only appearing to send people the messages they need at the proper time that they need it. There's surely some sort of quantum physics involved or most likely even beyond that. God only appears in color when he appears to give us a message... or when he wears his technicolor dream coat But, all in all, "God" is a spiritual entity and does not appear in color because he more or less does not 'have' an appearance. And I use "He" loosely, because who knows, it could be a he, a she, both, or none at all. Like I said, 'He' is spiritual by nature. Someone or something we believe in to drive and motivate us. Some make-believe presence that exists only because we believe in 'Him.' Hence the term "make-believe." If you build it, they will come.
completely invisible and without physical form. though of course, being all powerful, capable of taking on the appearance of anything. christian or not, that's something to think about any time you take for granted anything as being non-sacred. absolutely any thing.
the same one that every different name of any god or gods refers to. or to some aspect of. there are no false gods. just endless names for the same god no one knows anything about, nor ever has nor ever will.
the same colour as Adam.. who was made in God's image.... and made from the dust from the ground so God is the same colour as the dust on the ground :sunny: then no one has ever seen God.. according to John anyway ... so the whole question is superfluous :mickey:
