I would agree with that as someone who actually dyes the loose wool
that's made into carpets.
I would add though that you can get colour change problems that are
caused by the wool itself changing colour due to the sunlight, we keep
all out standard colour patterns in black plastic bags to prevent
bleaching.
This is more prevalent in very pale champagne type colours where there
is little dyestuff used and the shade is obtained from the natural
colour of the wool.
It could be of course that something has been spilt on the carpet and
the sunlight does indeed react with the spill making it more visible.
The O.P. could have a look at the WIRA (Wool Industries Research
Association) website at www.wira.com or Woolmark at www.wool.com where
there may be something relevant, be aware testing isn't cheap and could
be destructive.
