[Leica] M8 picture in magenta light

Mark,

Here's a challenge for you.  These are pictures of a still life which 
combines natural objects and synthetics.  The first picture gives a good 
rendering of the color:

Here's the Leica M8 shot with no filter:

You are welcome to try any standard global color correction on the second 
image to try to match the color of the first.  I can't find one.  Note that 
in the M8 rendition the grays in the pen and the plastic cap on the 90 mm 
lens are just about right, but the black pile jacket has gone magenta and 
the green pile blanket has turned gray.  The colors in the banana and the 
apple are a little muted, but the hues are close.

So it's not apples and oranges.  It's apples, bananas, anodized aluminum and 
synthetic pile, under an ordinary light bulb.
