> We could just as easily have called it "black" or "white" charge

And when we found a charge system that had 3 charges rather than just two, we did.

Where can I learn more on this? Searching yields nothing.

I imagine they're referring to https://en.m.wikipedia.org/wiki/Quantum_chromodynamics

Quarks and gluons, or quantum chromodynamics

Read up on “color charge.”

It's either six vs two, or three vs one, depending on what you mean by charge.

The quarks and gluons can be red, blue, green, antired, antiblue, or antigreen.

I was hoping someone would catch that ;)

It means someone is paying attention. When introducing the topic, it's more effective to say that electricity has 2 charges while chromodynamics has 3, and let them discover that those numbers are using different units for "2" and "3" only after they decide to find out more.

Carefully qualifying every single statement causes people to stop listening, because they don't care. It's better to correct oneself after-the-fact. Make it a topic of discussion once people are hooked. Introducing a simple error for someone to unravel does that.

That strikes me as a bad way to make a forum post.
