Derwent Lightfast Colored Pencils: A Safe Substitute for Prismacolor 931 Dark Purple

As much as I love my Prismacolors, they do have a few drawbacks.

One of my favorite pencils is Prismacolor 901 Dark Purple. Unfortunately, it scores poorly in lightfast tests. Even worse, Dark Purple has a nasty tendency to bleed through other colors.

Can Derwent Lightfast Pencils solve some of these issues?

I’ve been testing to find out!
