Sewing Project Color Advice

I’m making a little stuffed dinosaur. I have this deep green bubbly fabric I’m using for the body

It’s a very dark emerald color. I’m having a tough time deciding on an accent color to use for the spikes! Any suggestions?

Here’s what a finished dinosaur looks like, in case that helps

I usually just pick a minor color in the body fabric (I used dark green to match the stars in the cloud Dino) but since this fabric is a solid color, I can’t make up my mind! Help!
