This LoRa can handle color specification, dataset contained white, red and yellow Intgeras, but it seems to do all sorts of colors other than black (looks mostly blue).

Just use prompt: <color> integra, ..., <lora:integra_v1:1>

Recommended weight: 1

VAE I use: vae-ft-mse-840000-ema-pruned

For upscaler I recommend ESRGAN_4x or 4x-Ultrasharp, both give different but nice results, but that also probably depends on the model used.

First 3 images made with Noosphere and the other 2 with ChilloutMix.
