Every device I have just has a couple of blue ones and a couple of black ones, perhaps some orange ones and some USB-C ports, and good luck figuring out what they all can do. No symbols anywhere.
It's cool, the colors are just for aesthetics. Internally they're all connected to the same USB controller chip anyway.
/s probably
Edit: it was a joke. I know blue means 3.
If they're following the standard, which they often do but sometimes don't, white indicates 2.0 and blue indicates 3.0+. I think there are more but I don't remember the other colours.
