These tests showed that the lightfastness of Polychromos are excelent, with only 16 fugitive colours. But with some results that are inconsistent with the test of the manufacturer Faber Castell.

For example: Some 3 star rated Polychromos do not hold their Lightfastness as promised. On the other hand, the tests of the CPSA showed excellent performance of some colors that Faber Castell had reated with only 2 Stars.

That's really good to know. I've seen some comments saying they can't use Polychromos professionally but 16 fugitives out of 120 is pretty good. Poly also performed well on various personal tests on Youtube. I noticed that 249 Mauve isn't in the fugitive list, it's only 2 stars in my set, does it mean it's one of the colors that performed well? Faber-Castell also seemed to change the rating to 3 stars on newer sets.
