🎲 CR Random Multiline Colors

Documentation

• Class name: CR Random Multiline Colors
• Category: 🧩 Comfyroll Studio/🛠️ Utils/🎲 Random
• Output node: False

This node generates a multiline string of colors based on the specified type (hex color, RGB, or matplotlib xkcd color names), number of rows, and seed. It's designed to provide a simple way to create a diverse set of color values for various applications, ensuring repeatability with the use of a seed.

Input types

Required

• seed
  • A seed value to ensure the repeatability of the color values generated. Using the same seed will produce the same set of color values.
  • Comfy dtype: INT
  • Python dtype: int
• value_type
  • Specifies the format of the color values to be generated: hex color, RGB, or matplotlib xkcd color names. This choice determines the structure of the output color values.
  • Comfy dtype: COMBO[STRING]
  • Python dtype: str
• rows
  • Determines the number of color values to be generated, corresponding to the number of lines in the output string.
  • Comfy dtype: INT
  • Python dtype: int

Output types

• multiline_text
  • Comfy dtype: STRING
  • A string containing multiple lines, each representing a color value in the specified format.
  • Python dtype: str
• show_help
  • Comfy dtype: STRING
  • A URL providing additional help and information about the node.
  • Python dtype: str

Usage tips

• Infra type: CPU
• Common nodes: unknown
