Where can I find the colour hex or slider values of my Slugcat? (Using jolly co-op)

[haughty tree]

Hey! I use Jolly Co-op to come up with different slugcat colours and I've found a combination I like and would like to save for later to use at a later date.
Unfortunately though the customisation is done by sliding some sliders which have no in-game visible values attached to them, so I'm not sure how I'll be able to recreate it.
Is there a folder where my slugs colour (from Jolly Co-op) is stored?
Thanks
