Dark opaque vs Dark colors - transfer paper question

[Stargazer]

I'm looking at a few different auctions on Ebay. However, one seller is using the terms dark opaque for one auction and dark colors for another.

I've only ever heard light vs dark transfer paper. So, can anyone help a confused newbie? I want to make sure I get the right one. I want the dark transfer so all I have to do is trim and iron-on.
