It probably has no coloring toners in it then, which is good.

The cool inks used to benefit from the cyan pigment, which is very
lightfast.  However, these were the inks that had dye in them from the black
ink that was used to make the grays.

>I know yellow pigments are the weakest ...

Actually, the newer yellows are relatively good.  In my testing, the magenta
has been the weak link lately.  I was very interested to see that Cone's UC
test showed the UC magenta to be the best.  They must have come up with
something new.

>is it possible that some might be as good or even better than carbon?

Yes.  Note that Epson may even be moving away from carbon in its black
pigments.  They, of course, don't say what they are.  My chemist brother who
worked in carbon-related fields doubts that carbon is the ultimate.

But, today's inkjet colors are not, in general, as good as the carbon or
black pigs.  Note that Wilhelm's UC "B&W" numbers are better than the color
ones.
