Black is USB 2, blue is USB 3, and Orange or Yellow are usually “always on” and/or 2.4 amp or some other kind of thing like that.
Comment on Some basic info about USB

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.

Not on all vendors tho - coloring was an optional part of the standard. Dell often uses grey for USB3

It’s the variety and surprise here that adds novelty and excitement to life.

Apparently there’s also a teal (blue being USB 3.0, teal being 3.1), but I don’t think any of my devices actually use teal, regardless of what they support. Oh…hmm. Wait, I think my last desktop motherboard did that.
goes to investigate
Yeah, it has teal and blue ports.
My current motherboard just uses blue or red for everything, and labels them all in English as “USB 3.2”.
The red USB port is generally classified as USB 3.2, which was released in 2017. However, it can also be used to indicate a USB 3.1 Gen 2 port.
Another source of novelty and excitement.
Yellow USB Port Meaning
The yellow USB port is another color that can indicate either USB 3.2 or USB 3.1 Gen 2.
So much excitement.
The yellow USB port is more commonly found on laptops while the red USB port is more commonly found on desktop computers. This is because the yellow USB port indicates that it is always on, meaning it will continue to draw power even when the computer is turned off or in sleep mode. As a result, you can generally use it to charge other devices, such as smartphones.

I believe yellow or orange ports always deliver charging power regardless of device’s power state.

It’s cool, the colors are just for aesthetics. Internally they’re all connected to the same USB controller chip anyway.

If they’re following the standard, which they often do but sometimes don’t, white indicates 2.0 and blue indicates 3.x. I think there are more but I don’t remember the other colours.

Blue is a convention to indicate USB 3. Of course, not everyone actually implements that, and USB-C ports don’t, as far as I know, do that at all, just USB-A.
My current desktop does both – the case has USB ports on the top that come off a USB header from the motherboard, which have a simple number “3.0” pointing at its USB-A ports in front, but uses black plastic for them. The motherboard’s USB connectors in back use the “blue plastic” convention on its USB-A ports.
