Innoh_Create #1 - Color palette synthetizer
6/25/2025
☀️ Hello cultists! Here is a little update, not directly related to TTRPGs!
I’ve spent the last two weeks coding a small web app to help me create color palettes and conveniently import them into my favorite graphic software: Procreate. But the more I coded, the more I realized that this little tool could be useful for people other than me! So I decided to make it a real tool, hosted online and all!
So here it is:
Innoh’s Palette Synthetizer
The idea:
When I manually create palette for my illustrations, I initially select 3 colors, then merge them all together, using different shades and a multiply mode.
A picture's worth a thousand words:
_Sometimes some very beautiful colors emerge!
I always use the same process for all my illus so I was wondering if it was reproducible using CODE! (haven’t coded for over a year). I also wanted to take advantage of Procreate's palette import utility and no longer rely on an image from which I extract the colors with the eyedropper. So I had to create an app that allowed me to generate .ase files too.
The result:
After some tinkering and coding (in Typescript, using React), I’ve created this!
This little app generates a 30-color palette from the 3 you selected. There are different modes for the generation (the reducer modes) and different modes for how the final palette is arranged (the organizer modes)! It allows you to download a .ase file (for Procreate, for example) or a .aco (for Clip Studio Paint).
I’m pretty happy with the result because it really replicates the colors I tend to choose!
Cool things I learned:
-
Getting my hands again on React and Typescript. I was reeeally rusty!
-
Maths! I’ve learned how to calculate Carthesian products, and how to do K-means clustering!
-
Hosting a website, getting a domain name.
Now I really want to create other small apps! Especially for TTRPGs, idk, dungeons generators, npc creators!
Some inspiration:
You can share the palettes you created and all the parameters you chose using the Share button!
Here are some I found nice:
Blue Ribbon, Honey Flower & Chartreuse
Pomegranate, Golden Sand & Orient
Eeeeet voilà! Hope you’ll find this little tool interesting! Feel free to share your palettes in the comments! Here is the link again:
See you next article, this time probably about TTRPGs!
The cult is watching! ☀️
