AMAZING! That's so cool.
...and you now hold a special place in my heart as you're the first person to use my tool and show me the result. Thanks for sharing!
Thank you for the feedback! I've just posted an update with an early version of the colour palette system.
You can create a colour palette and save and load palettes from file.
Unfortunately you can't fully setup your color palettes with just a drawing pen as you'll need the keyboard for setting and deleting colours for now but I'll see if I can remove that restriction in future!
