WIP Wednesday: Queen of Color Roughs

Dear readers, I really need your help. While I love the general look of my Queens, the details are driving me crazy! Take colors. I'm trying to make two versions of the Queens- one with only the main inks and gold details, and one with a single main highlighting color. Let's have the Queen of Spades show us how that might look, roughly:

And I've been trying to keep to the primary colors (green is a primary color! The three-color model is outdated and wrong!). But that gives me a problem: If Heart is red, Diamond is blue, and Spade is green, what do I for Clubs?

Darker Green?

Purple?

Orange?

And for that matter, what animal do I give to the Queen of Spades, at the top of the post? Clubs has squirrel (well she will) Hearts has a fox, Diamond has a hawk..what can I do for my sword-swinging lady?

I appeal to you, might blog-o-sphere, for ideas!
