I don't know if it's just me, but occasionally my Krea 2 generations on the CivitAI generator glitch out and generate random, deepfried color garbage (like this, but usually even more abstract). Generally this is unusable and not worth posting even ironically, but I do think that the look is quite specific and neat.
So instead of throwing them away, I trained a style LoRA on them, so you can can apply the effect on purpose, likely partially and targeted. This obviously has the chance to completely wreck your generations, but if you're careful with it, you can do some cool stuff.
Note: The default approach is to call this pattern "abstract", because that's what it is. However, by not doing that you can get some very nice pattern hallucinations, either by letting the model decide or forcing it into something more concrete.
