A patented system of pure primary and secondary colors, in gradient steps, for calibrated additive or subtractive color mixing. The AMPAS recognized CalColor with an Academy Award for its unique ability to create pure, uncontaminated colors for camera. 

Rosco's CalColor Kit is the easiest way to incorporate and experiment with color in your imagery. The primary colors: Blue, Green, and Red; along with the secondary colors: Yellow, Magenta, and Cyan; and two intermediary colors: Pink and Lavender. Each color is available in four densities: 15, 30, 60 and 90, corresponding to the familiar 1/2, 1, 2 and 3 stop calibrations.
