Color changed (noise 1)

This uses the default model. For some reason the color changed for this image:

fossilsfromtheanthropocene

noise_scaled:

f

(see the gray area below the skull)

here uploaded inside a zip in case github changes (recompresses) the image:

fossilsfromtheanthropocene.zip

I'm not sure but how to check this but it could be completely unrelated to waifu2x. (Maybe some problem with the color profile.

It is maybe a problem related to color profiles and JPEG chroma subsampling.
Maybe a complicated problem. The original image already have color damage by JPEG chroma subsampling(especially red). And it seems that applying the original color profile failed for some reason.
I do not know the details at this time.

Here is noise1 result without applying color profile.
Red is close to the original, but the skeleton's shadow color is different.
