I used to work with pastels before seriously taking up painting. I greatly enjoyed the process but the pieces largely lacked the density, volume & mass that I prefer my work to posses.
Once I had obtained chops with my painting, I saw how I could have achieved the desired effects with the then abandoned pastels.
Like a lot of art things which become part of me/important to me, i fell into using colored pencils by complete happenstance. My painting showed me how to get what I wanted out of them much as it would have with pastels. There is a dichotomy to using colored pencils in that to get what i want out of them, i need to concentrate while also utilizing a looseness which I avoid with my painting.
For subject matter, rarely do I do portraits with colored paper. I prefer instead landscapes and cityscapes.
I prefer to use colored paper, either gray or brown. I vary the size with the largest being 9×12. I intentionally limit my color palette, each piece only mainly using varying shades of three colors with the tiny splash here or there of seemingly “wrong” colors. This i equate to the dissonant notes sometimes employed by Prokofiev and Monk.
Technique and conceptualization of colored pencil pieces are very different from my paintings. Having to utilize different approach & technique adds to how I think about painting. Aside from enjoying the process in itself, this gives it great value for me.
