3D Color Cube
The 3D Color Cube visualizes the color distribution of the signal in a three-dimensional space. Each pixel is plotted as a point in the selected color model, revealing clusters, gaps, and color casts that are hard to spot in 2D scopes.
If you use color pins, the 3D Color Cube also shows them as 3D markers inside the plot so you can see exactly where sampled colors sit in the current color model. (1.11.52+)
3D Color Cube in RGB mode
Color Models
Model
Description
RGB
Red / Green / Blue axes forming a unit cube — the native color space of the signal
CIE XYZ
CIE 1931 tristimulus color space — Y is photometric luminance, X and Z are the other two matching-function outputs. Signal is converted from RGB to XYZ via the active color space's matrix.
CIE Lab
Perceptually-uniform L*a*b* space derived from XYZ and a reference white (usually D65). L* is perceptual lightness; a* and b* encode the two chromatic opponent axes (red/green, yellow/blue). Unlike RGB or XYZ, equal distances in Lab correspond roughly to equal perceptual differences — which is why ΔE is computed there.
CHL
Chroma / Hue / Lightness cylindrical projection derived from Lab — same perceptual data, just in polar form
HSV
Hue / Saturation / Value cylindrical projection of RGB — convenient for content editing but not perceptually uniform
CHL (Chroma / Hue / Luminance) projection
HSV cylindrical projection
