I believe it has been established that:

Ektachrome (E6): fades *faster than Kodachrome* with time
Kodachrome: fades faster than E6 in projection

Are you sure that's not what it looked in the first place?  :-)

Kodachromes are supposed to last for centuries.  My E6 slides
from 1988 are fine with super vivid colors.  You must check
your storage conditions.  What kind of boxes?
