I want to make a cake with the same base color is the one pictured, what colors what I mix to make that?

It looks like Wilton navy blue...I would experiment with that + a very small amount of black...

(I like Americolor, but there's a few Wilton shades that I prefer...their navy is one of them)

I'm  sorry...this is the second time in 2 days that I've posted, messed up and couldn't edit!!

I'm watching "The Bachelorette" and should've waited to check my stash!

It's Wilton ROYAL Blue!
