RGB to HSV

Documentation

• Class name: RGB to HSV
• Category: Bmad/CV/Color A.
• Output node: False

This node converts RGB color values to HSV color space, enabling a different representation of colors that separates color hue, saturation, and value (brightness).

Input types

Required

• rgb_color
  • The RGB color to be converted to HSV. This input is crucial as it determines the color that will undergo the transformation from RGB to HSV color space.
  • Comfy dtype: COLOR
  • Python dtype: Tuple[int, int, int]

Output types

• hsv_color
  • Comfy dtype: HSV_COLOR
  • The resulting HSV color representation of the input RGB color.
  • Python dtype: Tuple[int, int, int]

Usage tips

• Infra type: CPU
• Common nodes: unknown
