Bubble chart color change

[#1]

I've created a bubble chart over a google map from a QVW I got from this discussion board.  I would like to change the bubble color but can't seem to figure out how.  The bubble color does not match the colors under Properties \ Colors. Can any one offer any advice for doing this?

you can change the color in the background color of the first expression

That’s it!  Thank you very much for the help.
