File format RGB FITS HELP!

Last night I was well out of my comfort zone....
I imaged with an OSC!!!!!!!!!!!!!!!!!!! a Meade DSI II colour CCD.
The trouble was, I didn't check what format Nebulosity was saving my files.
It saved (by default) in RGB FITS.

In hindsight, RAW FITS would have been better.
So, after several beers my hazy recollection of RGB reconstruction all
went to sh$#.

After calibrating out a master dark and then debayering I have no colour!
Where did the colour go?
After extreme saturation I can get some colour but I'm puzzled as to
why it is so washed out in the stack result before curves?

I don't have any of this trouble with the QHY8 OSC processing.

Then why the DSI II colour?

Hmmm...maybe colour aint my thing.

I thought I had a ball tearer set of colour to add to my mono full res set.
If I can't work this out it will have to be 3 more good nights with the mono CCD and filters.......

Ahh...back to my beer
