Adobe Color Books
Patchwork 3D supports color books used by Photoshop in the Adobe Color Book format (ACB). In the File Tab of the Patchwork 3D Settings, you can set the access path to the Adobe directory where these color books can be found.
Color books present in this directory are accessible via the Color Books tab in the color chooser. Select your color book from the drop-down list in order to access the colors.
