I really like this program! It could be a jam in its own right - '4-colour game jam', where you can only use a palette generated by this program. I'm still not sure what the 'mono' button does, does it just make the palette generate with a single colour? Nice one
A downloadable tool for Windows
With this tool you can generate minimalistic 4-color palette.
I tried to make it with hue, saturation and value shifting and many of generated palettes looks nice to me.
Play button is for generating palette every 2 secs. You can save palettes and they will be in dir with program.
