The following are changes currently implemented in development builds of Cyotek Palette Editor. Please note that these changes are not final and may be removed prior to the next stable release. If you have any comments about these forthcoming changes, please contact us.

Nightly builds featuring these changes are available from the Downloads page.


  • Added support for Adobe Color Table palette files
  • Added support for Microsoft RIFF palette files
  • Added new warning when saving palettes with a specific requirement (e.g. required number of colours) and the requirements are not met
  • The colour list now displays RGB values for swatches that do not have a dedicated name
  • You can now drag files directly from File Explorer into the Batch Conversion dialog
  • Added a new dialog for viewing available palette formats and their requirements
  • Added support for CMYK colours in aco files
  • The formats displayed on the Copy Colour menu can now be customised
  • Added CMYK support to the Copy Colour menu


  • Now requires Microsoft .NET 4.6
  • The Create Desktop Icon option in setup is no longer checked by default
  • Dragging a colour in the colour grid now automatically selects the colour if it isn't active
  • Add Swatch shortcut changed to Control + Shift + A to avoid conflicting with the standard Control + A shortcut
  • Setup now allows the selection of the file types to install


  • Removed the setup option for creating a Quick Launch icon
  • Due to offline help always being outdated due to the general weakness of the product manuals, the offline help files are no longer included in the setup, and requesting help will always display the online version


  • Some dialogs only supported local help requests and were unable to show help if the local help file was not available
  • Fixed an issue where the Save As dialog selected the first available format, ignoring the current palette format
  • Fixed a crash that could occur when sorting a palette by hue
  • Fixed an issue where some Adobe Photoshop Color Swatch files saved using the palette editor could appear to be fully black in other 3rd party applications. To fix affected palettes, simply re-save them using the updated Color Palette Editor
  • A newly required dependency was accidentally omitted from setup
  • After moving a colour by dragging it via the colour grid, the dropped colour is now correctly reselected
  • Deleting or cutting a colour via the colour grid couldn't be undone
  • Fixed a crash that could occur when attempting to undo the previous action
  • Fixed a crash that could occur when dragging into the Palette Editor from another application
  • If you initiated a drag operation in the colour list, then released the mouse outside the bounds of the list, no further drag operations could be initiated
  • Fixed a crash that occurred when non-RGB colours were selected in the colour list
