I'm tying to figure out what color gel would simulate a steet lamp. I know they have a green tinge when exposed with ambient light WB, but I want to do a shot of a guy in a garage with a strobe above him that is gelled to simulate a street lamp as seen by the human eye with the WB set to the flash setting. Any ideas?

Depends what type of street lamp. Sodium vapour lamps tend to be pinkish while high-pressure sodium lamps are more of a deep orange. It's fluorescent lights that have a strong green tinge compared to average daylight.

If the flash will be the main light source in the picture, then just leave it un-gelled and tweak the white balance in camera or in your RAW converter to get the colour reproduction you're looking for.

If your flash will be the only significant light source, then you don't need to worry about gels. Just shoot RAW and adjust the color temp and tint to get the color you're looking for (like Hermes said).

I intend to use ambient light for the fill for the scene, perhaps at an negative two exposure or so. I will use a flash to light the model and to give some highlights to the forground. I want to adjust the WB for the background and gel the flash so that it looks like a streetlamp I think I want a a slight orangish tint to the lamp; perhaps I will experiment with some sort of CTO filter.

Maybe stack a 1/2 CTO and a 1/2 tough plus green and go from there.
