This pack is based on the colors of a complete set of Copic markers, but usable as a Photoshop palette or any other program that can use .ACO files.
Each color is sorted into its color category and named after the corresponding marker. If there are typos, I apologize, after a few hours of extracting colors, I might have missed a letter somewhere.
Don't know what Copic markers are? See here: [link]
