There are individual differences of course, but cat colors do have some correlation with personality. People who work with animals often in rescue or other work often observe this. I've worked in rescue before and can agree.
Ones that I can think of off the top of my head:
- Orange: zany and spazzy
- Black: more chatty than you expect
There's also nothing wrong with having a preference. People can't adopt or take care of infinite animals, so we do need to have some way of deciding. Color, personality, expression, etc are all valid ways of choosing a pet.
As long as you're not discriminating against or attacking cats that's not your favorite color, I don't see an issue.
I assume they're talking about an Anbernic device. If you're interested in shopping around this channel on YouTube goes into the pros and cons of specific devices.
