The Warming and Cooling Kit consists of 4 CTO (color temperature orange) filters, 4 CTB (color temperature blue) filters, and 2 green filters.

Color correction filters are used to improve overall color balance in an image by adjusting the color temperature of the flash to better match other ambient light sources.

The newest addition to the ProMaster Modular Flash System, the ProMaster Flash Gel Kits can be used to add color to your light while using other ProMaster flash modifiers. Use these gels with the ProMaster Flash Extender (2609) and Portrait Kit (3928). This product must be used with a flash mounting ring (universal or dedicated).

Each kit includes different color gels in a transparent case with extra hook and loop dots.
