This node pack provides color space conversion between RGB and Oklab for Blender's Shader Editor and Compositor. Standard sRGB calculations can produce dark or muddy mid-tones during color mixing and gradient generation. Oklab operates as a perceptually uniform color space designed to closely match human vision. By converting colors to Oklab before performing mixing or math operations and converting them back to RGB, users can maintain accurate luminance and hue transitions. The nodes include support for both Lab and LCh formats.
