[Leica] Noct @F1 vs. color

[richard-lists at imagecraft.com (Richard F. Man)]

What I notice (duh...) is that at very low light where one needs the 
Noctilux at F1, or F1.2, the color contrast is very low, and typically 
there are color casts. Perhaps it's because I only shoot slides? Would 
color neg, like the Fuji Superia etc. be better? Or do I give up and just 
have to shoot B&W where the Noct' excels?

(A little moot currently since I sold my Noct' so I can afford a Tri-Elmar, 
but I suspect I may get another Noct at some point) Interestingly, on my 
personal favorite page, for my wife's pics, two are Noct's:
