I make a 2 color object. Acording to PS temperature view, the second color is printed with zero temperature:

But in fact it is printing ok:

This bug is probably related to #9597.

This is the painted object:

i had this exact issue as well, for me it actually wasnt printing correctly as it seems to be using color2 for the entire print at 'first layer' temps rather then the appropriate 'other layers' temp. if you use the default pla profile for a 2-color mmu print, change 'first layer' to 205 and 'other layers' to 215. that will make color 1 print at 215 for the entire print, and color2 will print at 205 for the entire print (rather then 215 as defined in 'other layers'). in 2.6 alpha 4 where this seems to be partially fixed, its not a huge deal, but in 2.5 and older, it actually sets the extruder temp at 0, but the actual temps are still tied to 'first layer' rather then the correct value of 'other layers'. maybe its not a huge deal in most cases, but it can change tip formation as in my experience, 215c seems to work great at tips, but 205 makes them too stringy.
