You tend to reduce overall contrast as well - after all what you are doing is the same as flashing, though affecting some colours more than others.
The difficult thing is predicting how much effect the colour will have (and therefore what exposure to give the pre-flash). It tends to affect every scene differently.

Turpin got the idea while looking out through a window with a green curtain on one side, and seeing the view through the reflection of the green material on the glass.
He built a prototype for the movie "Young Winston". The Lightflex was also used heavily on "The Wiz" (Ozzie Morris) and "Dune" (Freddie Francis).
The trouble is that since it affects the blacks and shadows more than the highlights, the amount of contrast in the final print or transfer to video will affect how much you can see the effect.
I've tested colored flashing using gels on the Panaflasher, but the effect was pretty subtle since I kept the flashing low.

As noted, flashing generally REDUCES contrast. The level of flashing (e.g., as measured by the density above "D-Min" the flash produces) and the exposure or "curve placement" of the scene information determines how much the flashing will affect the image.
