Hi Link....
I want to tell you bout the character and temperament, but guess what....? I think almost every RB I found have the same characters that been described by lots of pages. here is one of the page(*indirectly show my lazy side):

Because you ask, here attached the image of my baby girl... huhuhu.. She is quite dark almost similar to the RB that 'act' in Movie 'Cats and Dogs'. There also lighter color of RB, which look a bit silver with shiny coat. I never met any of light blue RB yet, and i really wish to meet one.
Btw, RB is kind of cat that cant be locked in a cage. and their body that build with amazing muscle not for them to just lie down and sleep. They are very active, smart and in a same time helpful. In my case, my RB always keep litter box clean and she also a good care taker to my other cat(I only have 2 cats).
And I guess RB is loyal too. Mine is very loyal. Everytime I reach home, she will always wait in front of my house door.My RB is very quiet but can be very loud when she need something. she hate to be hold, but she can be extremely cuddleble(is ths a word?lol) when she need me. Kinda good listener too. She is quiet, but will talk back if I am talking to her.
If you interested to know more, here is my baby profile page... hope some of photos & videos explained well bout her true character.
