For me, this is invalid for a DynamicBackColor formula.

I was able to finally resolve this by manipulating my data and using this:

="IIF( .T., RGB(b_red,b_green,b_blue), 0)"

Where, b_red, b_green and b_blue are fields in my cursor. I have no idea why it has to be this way. These Dynamic colors are finicky as hell. Same with the RGBComp() function that Marcia told me about. Got it working, but it wasn't easy.
