Trying out both Shellac & Gelish, want two similar colours from each brand?

[Courtney95]

So I'm trying to figure out whether to go with Shellac or Gelish as I have heard such good things about both & can't decide which to use! So I want to try them both out, is there two really similar colours so I can paint one hand gelish & one shellac and see which I prefer and get away with the same kinda of colour they don't need to match exactly but just so I don't have completely odd hands Haha any help will be great thanks xxx

I would think a solid cream black would match in both.
