ERROR_INVALID_COLORINDEX - 2022 (0x7E6)

The specified named color index is not present in the profile.

Updated: Feb 21, 2026

Overview

The ERROR_INVALID_COLORINDEX error code (0x7E6) is a specific technical error that indicates the system has encountered an invalid color index within a profile. This article provides detailed information on this error, its context, and how to diagnose and resolve it.

Technical Background

This error typically arises in scenarios where a color profile or palette is being accessed or modified. The Windows API uses color indices to reference specific colors within these profiles. When an invalid index is referenced, the system generates this error code to indicate that the requested operation cannot proceed due to the presence of an unsupported or non-existent color index.

Error Details

The ERROR_INVALID_COLORINDEX (0x7E6) error signifies that a named color index specified in a profile does not exist. This can occur when:

  • A color index is referenced that has been removed from the profile.
  • An incorrect or out-of-range index value is used.
  • The profile being accessed contains invalid data.

Common Causes

  1. Invalid Parameter Values: Incorrectly specified color indices in function calls or configuration files can lead to this error.
  2. Incorrect Object Type: Attempting to access a color index from an object that does not support it, such as accessing a text file's color profile instead of an image file.
  3. Corrupted Data: If the color profile is corrupted, it may contain invalid indices.
  4. Unsupported Operations: Trying to perform operations on unsupported or non-existent color profiles can trigger this error.

Real-World Context

This error commonly occurs in applications that handle graphics and image processing, such as photo editors, graphic design tools, and certain multimedia software. It is also relevant for developers working with Windows APIs related to color management and profile handling.

Is This Error Critical?

The severity of this error depends on the context in which it occurs. In most cases, it is not critical and can be resolved by correcting the invalid index or ensuring that the correct profile is being used. However, if the application relies heavily on accurate color representation, such as in professional graphic design tools, this error could impact the user experience.

How to Diagnose

  1. Review Operation Context: Ensure that the operation context is appropriate for the type of profile being accessed (e.g., image vs. text file).
  2. Validate Parameters: Check all parameters passed to functions related to color profiles, ensuring they are within valid ranges.
  3. Confirm Object Types: Verify that the object types being used support the operations intended.
  4. Verify Input Data: Ensure that the input data is not corrupted and contains valid color indices.
  5. Check Limits or Constraints: Confirm that no system limits have been exceeded, such as maximum number of supported colors in a profile.

How to Resolve

  1. Correct Parameter Usage: Ensure that all parameters passed to functions are correct and within the expected range.
  2. Adjust Operation Context: If the operation context is incorrect, adjust it to match the type of profile being used.
  3. Restore Data: If data corruption is suspected, restore or re-import the color profile from a known good source.
  4. Retry Operation with Valid Inputs: Attempt the operation again using valid inputs and indices.

Developer Notes

When working with color profiles in Windows applications, always validate input parameters and ensure that operations are performed within the supported context. Regularly check for data integrity to prevent issues like this from arising.

Related Errors

  • ERROR_COLORSPACE_MISMATCH: Occurs when a color space conversion is attempted but not supported by the profile.
  • ERROR_PROFILE_NOT_FOUND: Indicates that the requested color profile could not be located.
  • ERROR_PROFILE_FORMAT_NOT_SUPPORTED: The format of the color profile is not recognized or supported.

FAQ

Q: What does the ERROR_INVALID_COLORINDEX error mean?

A: It indicates that a specified named color index is not present in the profile being accessed.

Q: How can I prevent this error from occurring?

A: Ensure that all parameters are valid, and verify the integrity of your color profiles to avoid invalid indices.

Q: Can this error be critical for my application?

A: It depends on the context. For applications where accurate color representation is crucial, it could impact functionality.

Summary

The ERROR_INVALID_COLORINDEX (0x7E6) error code highlights issues with color index references in profiles. By understanding its causes and following diagnostic and resolution steps, developers can effectively manage this error to ensure smooth operation of their applications.
