Colour help needed!

Hi people who are more artistic than I am!

I need some help with the colour scheme of my brother's UTAU. Some of you might heard of her, her name is Jessic. (My bro's on OSUF under that name aswell.) He recently re-recorded her (CV/VC!) and I was working on her when I thought I have no colour scheme for her design...

This is what it looks like now (pic made by Erxenesh):

Spoiler:

Her hair is supposed to be dirty brown and her eyes are left: yellow, right: blue. That's all the coplour I know, so, do you guys know a good colour scheme for the rest of her design?

Thanks in advance.

Well, 'cus of the mechanical parts, I'm thinking gray or silver or gold, maybe... *thinks more*

Golden or coppered metal parts, and after, I'll see her dress in shades of ocher, her hair in Venetian blonde...And for her eyes, one turquoise and the other garnet

You could always go for a blue and gold theme, to match the eyes? Different shades of blue for the top and skirt, maybe bringing in another colour in places to break it up a bit, then gold for the metal parts and accessories... /ponders
