I assume you are referring to Clayton's comments:

"Some inks take on a greenish or magenta cast after a few months or even 
a few weeks.  Other brands initially produce a good black with a 
slightly warm, very pleasing tone, and then over several months change 
to an ugly chocolate colored brown.  The rate at which it changes is 
related to the amount of light the print is exposed to.  To my 
knowledge, as of this writing there is no gray scale inkset which does 
not color shift to some degree.  The good news is that the process seems 
to halt after a period of time and the prints exhibit excellent 
longevity after that."

I just want to point out that you need to take those in context...

Those comments are valid ONLY for pigment based GREYSCALE inksets..

OEM full-color inks in an 870 or 1270, for example,  will fade/shifting 
to the orange until all the original cyan dyes disappear. Airflow is 
actually more relevant than exposure to light on with those inks..

The bad news on that is old, but it's here:

As for the Lyson Small Gamuts, they are significantly longer lived than 
OEM EPSON dye-based inks, but dye-based inks (especially those on RC / 
glossy papers) generally need protection from not just light, but also 
from airflow...  Otherwise, as an earlier poster said:
" Lyson Small Gamut inks: the prints looked really nice. Especially 
those on Epson Glossy paper. The colours they are now vary from purplish 
to reddish to greenish".
