The Rogue Grid Gels feature twenty total choices including fourteen colors, five color correction and one diffusion option. Each gel is designed exclusively for the Rogue Grid (sold seperately) and attaches easily between the bezel and grid to add a splash of color, or to correct a specific light to balance with other sources. The set comes packaged in tabbed dividers with the gel name and the f/stop loss clearly visible, all of which stores inside the included padded storage pouch.
