Thanks so much for getting back to me.

I have no idea if Firefox does color correction. Quick googling
doesn't provide anything super obvious.

As a short cut, is there any way that I can make sure that my images
will not be color corrected?

The original site that I've made these demos off of does not
downsample images, they are served at exactly the size they're styled
at. I'll correct the main demo to reflect that.
