Yesterday I received my very first Prismacolor Lightfast pencils. Only 5 but enough for trying out and comparing.
My first impression and my later as well is that I like them but they are definately NOT comparable to their little brothers and sisters the Premiers.
Lightfasts are in my opinion much harder and the pigment is not that willing to stay on the paper. I made a diect comparison with Premiers - means nearly the same colors were compared.
Also the solving with both oil and Zest-It was not that nice. And I had problems to apply enough layers to achieve a look I am used to get with my "cheep" prismas.
Maybe it's the colors I used (cobalt blue hue, canary yellow, raw umber, diox. purple hue, neutral grey 2) and I had bad luck to order just the hardes colors but however - after using and comparing these I am sure I'll stand by my Prismas and Pablos - both are much better! Maybe not that lightfast - but I do not care about it because my art is not that good or precious - it is a problem of the future generations to conserve and restore the "masterful artwork" of Mrs Alberts. <--- me.
In the meantime I've heard that Sanford stopped producing these pencils and the 'lightfast' pencils will be incoorporated into the regular prisma line.
