This will invoke inner glow, bright colors and psychedelic feel. However it will need some effort to trigger. Keep in mind it is somewhat experimental and doesn't work on just anything. It is intended to work with photorealistic images.

Key properties are: add some photography negative / invert luminosity, add bright vivid colors, add contrast, add sharpness, adds bias toward monochromatic palette.

To trigger the effect you will need some kind of "light emission" concept in the prompt, like: "glowing aura", "backlight", "neon shine", etc. Also try to describe particular colors, like: "red lips", "green shine", "rainbow reflections'"... You will need to experiment. "pixeldust" was the trigger word used in training, but it doesn't seem to work well, at least not used alone.

Also you will need to find a right weight for the LORA, which may vary depending on checkpoint and prompt. Sweet spot will somewhere half-way to the point at which it just creates a negative image.

The LORA has been trained on a Pony checkpoint, but it works well on both SDXL and Pony. I'd say SDXL results are more interesting.

With SDXL start with 0.7-0.8 weight. With Pony start with 0.5.

I'll add comments stating used checkpoint and LORA weight. I'm using external generator and it's not apparently possible to add that data manually.
