I'd prefer if it was just the kimono itself, but for males as well as females. Not fabrics, but the actual kimono. I'm trying to find ones that are: grey, green, gold (or something that can pass for gold), and red.
I have found black/white gradient (not totally gray), lots of red, a very few of an olive green, and absolutely no yellow/gold spectrum in a google image search of "kimono."
Be aware, there are going to be several different styles of kimono from the era you look at and the class. Geiko will differ from maiko, as will samurai from noble, as will common from noble. The colors are most likely going to come from the entertaining class of women and the noble class of women from everything I've ever seen.
