The generated image is a cool tone,
When this image goes through the Ultimate SD Upscale node, it is output as a warm tone image.

How can I print it out in the original color?

You can try lowering the denoise value.

I was the first to change the Dinoise value, but it didn't change.

So, I thought it might be functional, so I uploaded it.

Then I would suggest using a different prompt for the ultimate upscale node.

Even if I set the mode to none, It comes out in a warm tone.
This color is not bad.

It seems that the influence of the tiled code has a big effect.
I think it's related to vae.

See if just encoding and decoding the image with the vae gives the same color tone shift. The vae could be biased. Anyway, I don't think it is something I can fix but I will experiment with it.
