FL-D filter?

Need some advice for a lighting situation. Shooting in a large retail store (about 1500 sq ft) with open floor plan; limited lighting package (couple of kinos and redheads); some daylight through windows on one side; fluorescent fixtures overhead.

Because of the size of the space, I'll probably have to rely on the overhead fluoros for ambient light. I plan to use daylight bulbs on the Kinos and half blues on the Redheads. My question is, should I use an FL-D filter to remove some of the green from the overhead fluoros? How would that affect the fleshtone of subjects that are lit with proper lights? I've never used an FL-D filter before.

flo tubes come in a wide range of CRI. its very hard to say until you put the camera up what you'll really need unless you have really trained yourself to see color temp / casts in lights. if they are 3200 and decent CRI, I'd block the windows with solids, or black plastic ($8-12) in a wide roll. killing the daylight will make shooting easier because then the light level thru the store will be more even.

that filter might help if you are stuck with low CRI bulbs that are greenish. might not be a bad idea to visit the location, and grab a few shots balanced at 3200,4300, and 5200 and see what looks best, then adjust your lights to suite. you can also do some minus green on the camera's matrix. you can't assume that the store flo's are greenish until you make a quick test.
