"Cat's Eye Nebula ... In real life, those wavelengths of light would be hard to distinguish for humans."
The context of the my comment was how the photo compare to the naked eye.
I used to take IR photos for fun (consumer camera with IR filter replaced with visible light filter), and used thermal and night vision technology at my job. They all relay useful information, but are not photo-realistic in anyway.
An IR photo of Earth for example, useful but not photorealistic.

I agree that is true for your example of the Cat's Eye nebulae. I guess my response was to my (and presumably other's possible) mis-interpretation that "ignore the color" was aimed at color astronomy images in general.

I imagine the Cat's Eye just looks like a bright cloud :)
