I cannot find out what reaction occurred during this, any help would be nice.
I had an old gallon pickle jar that I used for electrolysis of KCl that had a little bit of liquid in it and it froze one night. I let it turn back
to liquid and there was some precipitate that was stuck to the bottom. I'm guessing it was a little potassium hydroxide, potassium chloride, and
potassium chlorate. I diluted this with some water and left it until today.
Today I dumped some ASA (acetylsalicylic acid) partially dissolved in acetone into the jar. I looked at it about an hour later and it formed a creamy
looking layer and a more clear layer. This morning, I looked at it and it had changed colors to a pink/purple color! There is still two layers, a
white creamy layer and the larger pink/purple layer!
I attached a photo of what it looked like the next day.
Any idea what happened? I'm an absolute beginner so I have no idea, thanks.

Pretty color.
If you honestly care to find out, start by making well-defined mixtures of the chemicals you think are in there so you can consistently reproduce it.
As most organic chemicals and the ions you mention tend to be colorless/white, don't overlook the possible presence of metal ions in the residual
liquid that was in the jar (for instance from the electrodes you used).

Salicylic oxydation by chlorate probably result in auto condensation, maybe including aceton carbonyl but not for sure.

Looks the right colour for the iron(III) salicylate complex.

Thanks everyone, I'm going to attempt to reproduce it.
