No, I think its evidence that they can't find neutral with both hands, so 
instituted another mode instead. My goal is to find neutral with one hand (one 
holding a spectro) and build an ICC profile thats good enough to make the color 
mode neutral. So far my prints through the color mode are more neutral than   
prints through the B&W mode, plus all the other advantages of control and 
preview from the ICC process.

Its very interesting, and I plan to test it as soon as the requisite carts 
arrive, which may or may not be before Photokina...
