Yes good thinking VA.De Attrametis inks do
get a lot of good things said about them although they are very expensive & when I tried the their brown I hated the super red base of it & the total lack of vibrancy.I couldn't justify the expense to take experimentation any further through mixing ! PLUS
remember these are all waterproof inks so are no good for Magdalenes' working technique.
One artist who uses inks in a number of different ways & has published her findings for decades is Jamie Williams Grossman ,here she is on Noodlers but dig around in that blog archive there are more tests-
There is something else I feel I should bring up here on the subject of permanent inks -Often you will see ink being sold as permanent & it will say "it meets the international standard board organisation tests as being declared permanent. STOP RIGHT THERE !
those standards are for the purposes of signing legal documents etc. - It means that one with ill intent can not bleach, use a UV. lamp or chemicals etc to erase a signature or amount of money beyond recognition. It was not written for artists & their interests
it means next to nothing to us!
For many years lot's of artists have struggled with this with say, ballpoint pens when artists make a gloriously subtly toned masterpiece over a few weeks only to see the lighter toned parts of it fade into invisability in the same time or an ink wash do the same
Well it wasn't intended for that purpose nor do the standards they proudly display ever think it would be used diluted.
Even products made & specifically sold for artists - many paints (of all kinds), inks,pens,colour pencils etc. vary widely in their claimed lightfastness or waterproofness etc. There is no official body regulating or testing this at all !
There are moves to set up a internationally recognised scheme on these standards but it is proving hard to come into being.
For now, best is to test them yourself , - use a long established & well known brand -usually OK. but it does vary or worst of all cross your fingers & hope for the best
As an artist if you want to know whether an ink or even a paint is lightfast , then try it yourself
-if it remains OK. in a full sun window for a couple of months you are doing well, if it goes 5 or 6 months without visibly changing that is the best possible.
