In this article, I will show you two (2) methods to import an Adobe palette into GIMP. The first method is manual and, while it requires a bit more work, provides you with a lot of flexibility. The second method is a simple import/export process executed through sK1 -- a free and open-source, multi-platform drawing tool. The following recipes assume that you have an Adobe palette file (.ase) and you want to convert it to a format usable in GIMP.
Recreating the palette manually
To get started:
- Visit aseconvert.
- Import the palette (.ase) in the tool. This will result in a visual grid containing all the colors present in the original Adobe palette.
- Capture the result with a screen-grabbing tool.
- Open the captured image with GIMP.
- Open the palette panel.
- Click the Create a new palette icon at the bottom of the panel. This will open a palette editor dialog. It will start empty.
- Click the foreground color on the main dialog. This will open the Change foreground color dialog.
- Use the color picker in the above dialog to select the first color of the palette displayed on the screen.
- In the palette editor dialog, click the Create a new entry from the foreground color icon. This creates a matching color element of the target GIMP palette.
- Repeat the last two steps until all colors of the source (.ase) are in the new GIMP palette.
- Click the Cancel button on the foreground color chooser dialog to close it without changing the active foreground color.
- Give the new GIMP palette a name.
You are done: the new palette is now available from the Palettes dialog.
Converting the palette automatically using sK1
- Install and/or open an instance of sK1.
- Go to Edit > Preferences.
- Click the Palettes vertical tab.
- Click the Palette management horizontal sub-tab.
- Click the Import button and select the .ase file you want to convert.
- Click the Export button while on the new imported palette
- From the dropdown selection field on the bottom right, choose GPL - GIMP palette file as an output format.
- Rename the palette file and provide it with the proper extension (.gpl).
- Hit Save.
You are done; the new palette file is ready to be added to your GIMP collection.
Bonus: a command-line solution
You can install and use Uniconvertor to convert color palettes directly from the command line. In my experience, the tool is multi-platform (Mac, Windows, and Linux), supports multiple file formats, and works as expected.
