Right, but here, in these specific JPEG images, the "red tint" is a, hmm, red herring, right? Presumably these images are monochromatic in some IR band, and red tint added for PR reasons? The color does not convey information, I'm guessing? Or are these images genuinely stacked from a few sub-spectrum images? If so, what exactly is the hue of the colour? If it's the former, I'm always amazed how much effort goes into making space exploration eye-popping. Artists' renders of spaceships and exploding supernovae, tarted up space telescope pictures and so on.
