RGB to HSV

Documentation

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

The node converts RGB color values to HSV color space, facilitating color transformations and analysis by separating color hue, saturation, and value. This conversion is essential for tasks that require color space manipulation or analysis, such as image processing and computer vision applications.

Input types

Required

• rgb_color
  • The RGB color input that needs to be converted to HSV. This parameter is crucial for the conversion process, as it represents the color in RGB format that will be transformed into its HSV equivalent.
  • Comfy dtype: COLOR
  • Python dtype: Tuple[int, int, int]

Output types

• hsv_color
  • Comfy dtype: HSV_COLOR
  • The output HSV color, represented as a tuple of hue, saturation, and value. This conversion is useful for applications that rely on the HSV color space for more intuitive handling of colors.
  • Python dtype: Tuple[int, int, int]

Usage tips

• Infra type: CPU
• Common nodes: unknown
