How to paint gold?...well, I have seen students, and myself, crumble at times...this was today's effort and a few golden oldies from a few weeks past. Yesterday this cast wasn't looking so golden.
So how to paint gold? Concentrate very hard around subtle shifts of value. Don't paint the mid-value, base too light on the light side of the form, or you will have no place to add the ZING later. Look for green and purples in the shadow sides. Anything other than yellow. Block-in the light side with a dullish yellow like raw sienna, then start building up the gold with, say, a bright cad. lemon yellow and white mixed with a very light clean cool green. Think GOLD very last.
