This feature is still experimental. If you encounter operations that remove the alpha channel from a colour unexpectedly, please contact us.

Alpha channel support is a rarity among older palette formats, and the option to edit the alpha channel is therefore disabled by default.

Enabling the use of alpha editors

To toggle if the user interface provides options for editing alpha channels

  • From the Options dialogue, choose the Editor category
  • Check or uncheck the Show alpha channel editors option


Even if the option to display alpha channels is disabled, Colour Palette Editor will try to preserve the alpha channel where possible.
