I've move on from color to simple concept, I'm having difficulty with choices and model compatibility, I'll work on it more. (Also I am working on butterfly mouth at the moment too.)

Important: Pink/red flowers may be fixed as mouth with Adetailer, please use the "mediapipe_face_mesh_eyes_only" option.

What does it do?
It generates a flower on the mouth. It's like a person holding the flower with the mouth (not by the stem). It will not work on full body generation.

What are the triggers?
The main triggers is: fl0werm0uth.
The colors can be customized by adding [color] flower, e.g black flower, purple flower, etc.
Optional add-on prompts: 1girl, portrait, floral background

Recommended Weight
The weight is good from 0.5 to 1.0 (or slightly more).
0.5 may not have flowers, 0.7~0.8 seems the best.

Recommended model:
I would suggest anime/2.5D model, realistic model messes with the mouth too much.
It can give amazing result when paired with other floral type loras.
