ColorHSV

Python object: phenotypic.schema._color_hsv.ColorHSV

Robust HSV summary for a colony.

HSV hue is circular and HSV is not perceptually uniform, so the robust center is computed as the geometric median of cone-Cartesian coordinates (S*V*cosθ, S*V*sinθ, V) and converted back to H,S,V. HSVConeVariance is the trace of the cone-Cartesian covariance.

Column label	Description	Type
ColorHSV_HueRobustMean	Hue of the cone-embedded geometric-median robust center (circular-correct)	Tier 2 · Descriptive trait
ColorHSV_SaturationRobustMean	Saturation of the cone-embedded geometric-median robust center	Tier 2 · Descriptive trait
ColorHSV_ValueRobustMean	Value (brightness) of the cone-embedded geometric-median robust center	Tier 2 · Descriptive trait
ColorHSV_HSVConeVariance	Trace of the HSV cone-Cartesian covariance (single 3D HSV spread scalar); spread about the arithmetic mean of the cone coordinates (NOT about the reported RobustMean center)	Tier 2 · Descriptive trait
