That's easy to answer.  They are going to fade and color shift.

Of course, it's all relative.  Depending on the multitude of factors, one
can limit the fading and color shifting significantly.  I'll publish the
fade test results that include my latest attempt at a more stable mix.  (The
test ends Monday.  So look for it Monday evening.)

Of course, my tests just give relative results in my fast, bright florescent
light fader.  I feel that such tests are better than nothing, and they are
about the only way to get results fast enough to have any value in our
lifetimes.  So, I'm going to base what I do on them regardless of the
uncertainties.

You know the current batch of pigments will warm shift.  So, just figure
that shift into your strategies and go for it.

Don't hold your breath.  Epson is your best shot with this, and you can see
what we got with the EAM "response" (almost none).
