I bet you'd have trouble believing how controversial the proposal to add
colour capability to FITS is. However, this question continues to rear
its colourful head.

Never mind. You will find my initial thoughts on how it should be done

Mark,

I just reread that. I can see that. You're talking about something
like Wien's law, or maybe Wien's law in false colors, or maybe perceived
colors. My understanding of the OP's question/interpretation is that
there's color information intrinsic to FITS images (or FITS data arrays
of any sort). If I use something like GAIA (Dave Berry, comment
appreciated) I can set my color pallette (sp?), I can cut levels
to bring out the details I'm after, be they astronomical or instrument
intrinsic faults (like channel edges, a problem we're in the process
of trouble shooting), I can cut lines across and do a lot more things
that have nothing to do with color. Where I'm at I find e.g. ellipticities
of images (or rather getting rid of them) much more interesting than
colors. (Dave Berry, concerning GAIA, I'm perfectly happy with our
default color scheme)

Aloha,

Maren
(UKIRT instrument (control, not data reduction) s/w eng, currently
mostly dealing with WFCAM operations issues, which aren't even
image quality, in spite of that I should be doing CGS4 development
work - and not speaking for my employer here)
