    I may have to use a situation with a flourecent cool white light (cool white bulbs). What gel do I need to change the color temp to 3200K?

    It’s not an exact science, despite what theory may dictate.
    Try Roscolux #3411 – “Roscosun 3/4 CTO”, or
    Roscolux #3407 – “Roscosun CTO”.
    You should have some Roscolux #3314 – “tough 1/4 minusgreen” handy also.

    Cool white lamps are about 3400k

    I find it best to use Rosco 3314 gels – 1/4 Minusgreen
    As the name implies it reduces the green wavelengths in cool white lamps. The gels are magenta in color
