Pico-8 is an awesome fantasy console by lexaloffle. I really wanted to use the palette in other pixel art editors so I made a clr file, to be used with the standard color picker under OSX.
How To Use:
Download the pico8.clr
Copy the file to ~/Library/Colors/
If you open your color picker (for example in the amazing pikopixel pixel art editor) you will be able to find it in the drop down menu under the ‘Color Palettes’ tab.
