As I've done this one before, I thought I try something a bit different...
So I tried the 3 colours spaces RGB, LAB & HSB in CM
and then autoLevels and Dan Margulis's severe Shadow/highlight action.
Just to give Greg something to do (!), here they are all, in no particular order - can you identify them all?

Is it the light bulbs that make getting the color right on the upper level of the merry go round so difficult?Sometimes the bulbs seem yellow on strips of red.Ganna and Zog have gotten brightness and detail down but seem one tweak from perfect color.GregM

No - but then life has been a bit stange at the moment as I've just built my first PC (!) and so things may have fallen down the crack!

I have a technical question - Mike/Greg,
One of the points that has been made is that saturating colours in Lab is clean and you do not get posterisation (if that's the correct term) - no sudden breaks of colour. I guess this has a lot to do with how PS (and CM?) attempts to convert from the invisble Lab channels to the screen's RGB (and also when changing mode) - true?
But if you do it in RGB it can be pretty bad (to get the same level of colour).
Using PS Saturation can be the same or worse.
How does HSB compare in these stakes?

My partial answer is that Lab can create colors that RGB cannot support...
So it can "fill in the blanks" a bit more..Mike is going to bhave to answer the under the hood HSB and PS aspects of it...
I will say that in the pinning areas of CM you have to be careful that you do not expect too much of a LAB pin.
