After trying several papers over the years, I think I’ve finally found my preferred support for colored pencil:bristol board with a vellum finish.
Bristol vellum has just enough tooth for adequate layering, but not so much that the tones look overly grainy without burnishing.(Depending on the subject matter, I often prefer a little graininess when working with pencils.)I’m also able to achieve what I want to with more defined pencil strokes.
Light graphite erases from bristol vellum relatively easily, and I’m able to adequately lift color with a kneaded eraser.My kneaded eraser is as important a drawing tool as any pencil, so the latter benefit is important.
The other side of the bristol vellum I’ve used has a smooth finish, although I found that it’s too smooth for adequate colored pencil layering.However, I understand that a smooth surface like this works well for photorealistic graphite drawing, which I have yet to test for myself.
