... that there were two cels of the same design 
painted with different colors.  At this point, 
Void-chan is being attacked by Syaoran's thunder 
magic, and there's a lot of F/X in which she's 
normal-colored, then all white in the next frame, 
then nearly transparent, then half-normal, and so 
on, as the lightning bolts flash around her.  So 
I'd guess that A14 is the "normal" Void and A14/1 
is the "thunderstruck" Void painted from the same 
douga.  

Most of my CCS primes are correction layers that 
were painted to overlay another one.  But I do 
have some non-correction "primes" from the Ep. 1 
scene in which Sakura seals The Fly.  Again, 
there's changes in lighting, in which I'm 
guessing the same bank of dougas were painted 
twice, once normally, and once in silhouette.
