LoyceV is a bot. Bots don't do anything manually!
By the way, have you read his colored text?
I obviously read his colored post and this is the main reason for my curiosity for my question. It’s mind blowing to think that he will manually type all this bbcode color code since it’s not available as default in the forum. I hope this is already not Off topic on this thread considering that this is all about text color discussion. Sorry @jackpotracer for slightly hijacking your thread.
Afaik Signature code frequently use hex format if you look at the bbcode of all the signature design in the forum.
