Innovative Color Remapping

Core to ColorSynth’s toolset is an elegantly designed collection of innovative color remapping tools called Color EQ. Color remapping tools have been around for decades; however, the mathematics usually result in unwanted color distortion artifacts that impede their usefulness and usability. ColorSynth’s Color EQ nodes have been carefully engineered to address these issues and to deliver enhanced possibilities to all users.

(3) Color EQ nodes

The Master EQ works as a parametric audio EQ, with all the necessary permutations of Hue, Lightness and Saturation remapping. The 7-band EQ is a specialized tool designed to modify the hue, lightness and saturation of complex conditional color qualities. The Color Mixer allows super clean RGB-based remapping of (9) color bands.

ColorSynth - intuitive Color Grading

Simple at first glance, ColorSynth is an elaborate pre-wired network of color processing nodes totaling more than sixty items arranged in an eight-layer stack with several sublayers. Regardless of the complexity of the grade, ColorSynth renders the results in floating point precision, at a constant speed, in both SDR and HDR. The ColorSynth grading template is designed to meet the user at any comfort level; from the simplest One Light pass to the most esoteric needs, the ColorSynth software is easy to learn quickly.
