This collection provides utility node groups for advanced color operations within Blender's shader editor. It includes tools for exact and approximate sRGB to linear conversions, which are particularly useful for correcting colors generated procedurally via Color Ramp or Combine HSV nodes. The pack also features dedicated Combine and Separate HSV nodes that integrate the appropriate color transformations automatically.

Additionally, the package introduces support for Oklab, a perceptual color space designed to closely match human vision. These Oklab utilities allow for smoother color blending without unwanted intermediary hues, more predictable hue rotations on highly saturated colors, and desaturation methods that accurately preserve perceived lightness.
