I had a little look back in the previous customisation thread & it looks like a few of the pictures from
this post still work. I'm not sure that those are the pictures we did end up going with for the current graphic though. Or if there are now other pictures available? I did find
these from season 2 but that isn't many characters.
I did a quick look around & found these:
Patrick Jane
Teresa Lisbon
Grace Van Pelt
Wayne Rigsby
Kimball Cho
Dennis Abbott
Kim Fischer
Jason Wylie
Michelle Vega
Misc. Collection (may be duplicates to pictures in above links)
Is that all the correct characters?
For your colour scheme are you thinking any other colours other than the colours from the cup? I did quickly put together
this based on the colours from the first picture &
this from the second picture
