HEX to HUE Node Description

Converts hexadecimal color code to hue value for AI artists, aiding color manipulation and analysis.

HEX to HUE Node:

The HexToHueNode is designed to convert a hexadecimal color code into its corresponding hue value, both in degrees and normalized form. This node is particularly useful for AI artists who need to manipulate or analyze colors in their projects. By converting a hex color to its hue, you can better understand the color's position on the color wheel, which can be essential for tasks such as color correction, color grading, and generating harmonious color schemes. The node simplifies the process of extracting hue information from a hex color, making it accessible even to those without a deep technical background.

HEX to HUE Node Input Parameters:

color_hex

The color_hex parameter is a string that represents the hexadecimal color code you want to convert to a hue value. This parameter is essential as it serves as the input color for the conversion process. The default value is #00ff33, which is a shade of green. The hex color code should be in the format #RRGGBB, where RR, GG, and BB are two-digit hexadecimal numbers representing the red, green, and blue components of the color, respectively.

unique_id

The unique_id parameter is a hidden parameter used internally to ensure the uniqueness of the node instance. This parameter is not required to be set by the user and is managed automatically by the system.

HEX to HUE Node Output Parameters:

string_hex

The string_hex output parameter returns the original hexadecimal color code that was input into the node. This allows you to verify the input color and use it for further processing if needed.

float_hue_degrees

The float_hue_degrees output parameter provides the hue value of the input color in degrees. This value ranges from 0 to 360 and indicates the color's position on the color wheel. For example, 0 degrees corresponds to red, 120 degrees to green, and 240 degrees to blue.

float_hue_norm

The float_hue_norm output parameter gives the normalized hue value, which is a floating-point number between -0.5 and 0.5. This normalized value is useful for certain mathematical operations and color manipulations where a normalized range is preferred.

string_hue_degrees

The string_hue_degrees output parameter returns the hue value in degrees as a string. This can be useful for displaying the hue value in user interfaces or for logging purposes.

string_hue_norm

The string_hue_norm output parameter provides the normalized hue value as a string. Similar to string_hue_degrees, this is useful for display and logging purposes.

HEX to HUE Node Usage Tips:

  • Use the color_hex parameter to input any hex color code you want to analyze. Ensure the format is correct (#RRGGBB) to avoid errors.
  • Utilize the float_hue_degrees and float_hue_norm outputs to understand the color's position on the color wheel and for further color manipulations.
  • The string outputs (string_hue_degrees and string_hue_norm) are handy for displaying hue values in user interfaces or for logging purposes.

HEX to HUE Node Common Errors and Solutions:

Invalid hex color format

  • Explanation: The input hex color code is not in the correct format (#RRGGBB).
  • Solution: Ensure that the hex color code is a string starting with # followed by six hexadecimal digits.

Color conversion error

  • Explanation: An error occurred during the conversion of the hex color to hue values.
  • Solution: Double-check the input hex color code for any typos or invalid characters. If the problem persists, try using a different hex color code to see if the issue is specific to certain colors.
