Exploring Muted Color

I've been thinking a lot about color lately, and working out color combinations with Prismacolor pencils. These are two sketches using muted color. I'm working out what colors I will use in future etchings.

These sketches use shades of purple, brown, grey, and pink. These nonobjective designs start with a small central rectangle and grow outwards. The first drawing has a dominant horizontal axis. The second drawing balances the horizontal and vertical axes. Both drawings rely on some diagonals to add a feeling of movement.
