Can I bring my color palettes from other apps to PaintCode?
You can copy & paste and drag & drop colors from many other Mac apps such as Apple Color Picker, Pages, Numbers and Keynote. It also works in reverse: you can copy & paste and drag & drop colors from PaintCode library to such application. Essentially, all Mac apps that correctly use system pasteboard for encoding colors (using the NSPasteboardTypeColor) are compatible with PaintCode.
PaintCode also imports saved palettes from Photoshop (.aco file) and Illustrator (.ase file) - just drag & drop such a file to PaintCode library.
