ComfyUI Node: 🎲 CR Random RGB Gradient

🎲 CR Random RGB Gradient:

The CR Random RGB Gradient node is designed to generate a gradient of random RGB colors based on a specified number of rows and a seed value. This node is particularly useful for creating visually appealing and unique color gradients that can be used in various artistic and design projects. By setting a seed value, you can ensure the reproducibility of the gradient, making it easier to achieve consistent results across different runs. The node's primary function is to produce a multiline text output where each line represents a row in the gradient, with each row containing a random RGB color value. This allows for easy integration and manipulation of the generated gradient in your creative workflows.

🎲 CR Random RGB Gradient Input Parameters:

seed

The seed parameter is an integer value that initializes the random number generator, ensuring that the sequence of random numbers (and thus the generated gradient) is reproducible. This means that using the same seed value will always produce the same gradient. The seed value can range from 0 to 0xffffffffffffffff, with a default value of 0. Setting a specific seed is useful when you want to recreate the same gradient multiple times or share it with others.

rows

The rows parameter specifies the number of rows in the generated gradient. Each row will contain a unique random RGB color value. The number of rows can range from a minimum of 1 to a maximum of 2048, with a default value of 5. Adjusting the number of rows allows you to control the granularity and length of the gradient, making it suitable for different artistic needs.

🎲 CR Random RGB Gradient Output Parameters:

multiline_text

The multiline_text output is a string where each line represents a row in the gradient. Each line contains a random RGB color value in the format value:R,G,B, where value is a number indicating the position in the gradient, and R, G, and B are the red, green, and blue color components, respectively. This output can be used directly in your projects or further processed to create complex visual effects.

show_help

The show_help output is a string containing a URL to the documentation or help page for the CR Random RGB Gradient node. This link provides additional information and guidance on how to use the node effectively, making it easier for you to understand and leverage its capabilities.

🎲 CR Random RGB Gradient Usage Tips:

• To create a smooth and visually appealing gradient, experiment with different seed values and row counts until you achieve the desired effect.
• Use the multiline_text output to easily integrate the generated gradient into your design projects, such as backgrounds, textures, or color schemes.
• Refer to the show_help link for detailed documentation and examples on how to use the node effectively.

🎲 CR Random RGB Gradient Common Errors and Solutions:

"ValueError: Seed value out of range"

• Explanation: This error occurs when the seed value provided is outside the acceptable range (0 to 0xffffffffffffffff).
• Solution: Ensure that the seed value is within the specified range. Adjust the seed value to be between 0 and 0xffffffffffffffff.

"ValueError: Rows value out of range"

• Explanation: This error occurs when the number of rows specified is outside the acceptable range (1 to 2048).
• Solution: Ensure that the rows value is within the specified range. Adjust the rows value to be between 1 and 2048.

"TypeError: Invalid input type"

• Explanation: This error occurs when the input parameters are not of the expected type (e.g., non-integer values for seed or rows).
• Solution: Ensure that the seed and rows parameters are integers. Verify the input types and correct any discrepancies.
