There are hundreds of reasons why I love to work on toned papers. I had to share one with you today. I was working on a page in my 2011 fake journal and had leftover rubber stamp ink on my palette. I quickly speared some of it on a page spread in my regular journal.
On the toned paper the color pops!
This is true whether you are working with gouache, acrylics, colored pencils, or, as I was above, with rubber stamp inks that are pigmented (and not transparent).
Toned papers are also great for sketching because you already have your middle tone and can work up to your highlights and down to your shadows.
If you don't like having a steady diet of toned papers in your journal simply take your white paper pages and prepaint some of them with lovely, rich tones you can paint over.
