I'm looking at a graph I downloaded off Kodak's site 
that shows the spectral sensitivity of Kodachrome 25.  
The ordinate is log sensitivity and the abscissa is
wavelength in nanometers.  The cyan-forming layer 
has a peak sensitivity of +0.5 at 650 nm and has a 
sensitivity of -2 at 500 and 700 nm.  The magenta-
forming layer has a peak sensitivity of +0.5 at 565 
nm and a sensitivity of -2 at 615 and 460 nm.  The 
"yellow"-forming layer has a peak sensitivity of +1 
at 425 nm and a sensitivity of -2 at 540 nm.  Zo...
It looks to me like you would want to use colors 
which are made by the cyan- and yellow-forming
layers and which are not mutual to the two of them.
However, I don't know what to do about the sensitivity
of the magenta-forming layer other than to try to stay
outside of it as best one can.
