Can anyone tell me how to copy a color palette in Corel X6 from one computer in order to install in new computer?
Are you talking about a custom palette? Or one of the palettes included with CorelDRAW?
In my copy of X7, it sees my custom palettes in a "My Palettes" folder in my user Documents folder, e.g.,:
C:\Users\[my user name]\Documents\My Palettes.
