it was mostly the red this show does not like red

Probably weird question, but does anyone else have kind of “colour theme” for their dog? Like some colour they get more in the stuff for their dog? Not necessarily even the main colour but one that shows up in details of the collar, lead, harness etc or something?

My dog has mostly reds, I think bold red is good colour match for his personality. I didn’t even aim to get red stuff, it just kinda happened. Only his lead and harness are black.
