Helmlab: A Two-Space Family of Analytical, Data-Driven Color Spaces for UI Design Systems
arXiv CS.CV

ArXi:2602.23010v3 Announce Type: replace-cross We present Helmlab, a family of two purpose-built color spaces for UI design systems sharing a common 11-stage analytical structure: MetricSpace, a 72-parameter space optimized for color-difference prediction, and GenSpace, a 44-parameter space optimized for gradient and palette generation. The forward transform maps CIE XYZ to a perceptually-organized Lab representation through learned matrices, per-channel power compression, Fourier hue correction, and embedded Helmholtz-Kohlrausch lightness adjustment.
