you could always mix the gold and silver or mix pearlescent white with gold to make a pale ,pale gold, or brush over the gold with pearl white…. think of the white curls and their softer pastel gold… that way the silver wouldn’t fade into the white or look too gray, and you’ll have a little bit of pop from the gold to contrast the purple…… hmmmmm….
Yeah, I wouldn’t use gold. The gold would be the brightest thing on there, it would pull away from the rest of it. Silver is good, and the idea of a toned down pearl gold might work well too.
