 The basic anthropomorphic form varies . Child gods are depicted nude , as are some adult gods when their <unk> powers are emphasized . Certain male deities are given heavy <unk> and breasts , signifying either <unk> or prosperity and abundance . Whereas most male gods have red skin and most goddesses are yellow — the same colors used to depict Egyptian men and women — some are given unusual , symbolic skin colors . Thus the blue skin and <unk> figure of the god <unk> alludes to the Nile flood he represents and the nourishing fertility it brought . A few deities , such as Osiris , Ptah , and <unk> , have a " <unk> " appearance , with their limbs tightly <unk> in cloth . Although these gods resemble mummies , the earliest examples predate the cloth @-@ wrapped style of <unk> , and this form may instead <unk> back to the earliest , <unk> depictions of deities .
