Strange color shifts for custom data (histopathology images)

[NicolasNerr]

Hello,

I am using the repo to produce synthetic histopathology images.

However, I am observing a weird color shift during training. As training progress, this shift is getting worst and worst. Basically, the images I am working with are all kind of pinkish, but produced samples are sometimes in this range, but can also be yellow, green, red, etc...

Is this a problem that has been observed before with diffusion models ? If yes, is there a know solution or an explanation for this behavior ?

Thank you so much !
