Lacey,
At first I thought you might be interested in painting your studio wall with the same color, as I did. The paint can be formulated by Benjamin Moore according to the formula posted by Michael Georges in this thread:

Benjamin Moore & Co.
319-3B
UTC Gallon Formula
OY 3x20.50
BK 2x15.00
OG 0x17.00
GY 0x10.75
It's a fine color for a studio backdrop, and as far as I know it is the same wall paint in use in several well known artist's studios. As I said, I have this color on my walls. I think Mr. Whitaker does too.
For whatever it is worth as far as formulas go, here is the formula in Photoshop! I scanned the wall color with my Gretag-MacBeth Eye-One color spectrometer.
Now you have the Formula!
