Thanks for diving into the old thread - you saved me the trouble.
I'm terrible with colors, so I purposefully didn't suggest any others. The teacup is iconic,. but I trust the graphics team to come up with combinations that work with it. That said, I think I like this group better -

Since the show has been off the air for some time, I doubt there ane any newer pics to find. A couple of suggests - don't use a pic where Cho is smiling. His character is famous for never smiling. And I would not include Kim Fischer. She was never really a regular.
I would like to see the romantic couples positioned together - so Jane and Lisbon in the middle, maybe Grace and Rigsby on one side and Wylie and Vega on the other with Abbott and Cho on opposite sides on the extreme outside.
