blendLuminosity: HSV Channel Isolation

Hue-Saturation Preservation System

Luminosity blending isolates and replaces brightness values while maintaining color identity through HSV color space manipulation. Base colors contribute hue and saturation components; blend colors provide only luminance data for final composition.

$$HSV_{result} = (H_{base}, S_{base}, V_{blend})$$

Component	Source	Description
Hue	Base	Color wheel position preserved
Saturation	Base	Color intensity maintained
Value	Blend	Brightness replaced completely
