🎲 CR Random RGB Gradient

Documentation

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

This node generates a multiline text string representing a random RGB gradient, based on a given seed and the number of rows specified. It aims to provide a simple way to create diverse and random color gradients for various applications.

Input types

Required

• seed
  • The seed parameter initializes the random number generator, ensuring the reproducibility of the gradient pattern. It plays a crucial role in generating consistent results across different executions.
  • Comfy dtype: INT
  • Python dtype: int
• rows
  • The rows parameter determines the number of color steps in the gradient, affecting the gradient's smoothness and complexity. It directly influences the length and variation of the generated multiline text.
  • Comfy dtype: INT
  • Python dtype: int

Output types

• multiline_text
  • Comfy dtype: STRING
  • A string containing multiple lines, each representing a step in the RGB gradient with random colors.
  • Python dtype: str
• show_help
  • Comfy dtype: STRING
  • A URL string providing access to additional help and documentation related to the node.
  • Python dtype: str

Usage tips

• Infra type: CPU
• Common nodes: unknown
