Getting Started - Swatches

I'm just getting underway on a new piece.  It has an interesting panoramic crop, which is somewhat different for me, with a final planned size of 26" W x 12" H.  I'll be working on my favorite paper, Colourfix, in a color that I haven't used much: Aubergine (usually I work on Storm Blue or Fresh Gray). The first step is always to pick my palette, and I like to do this by laying down swatches of color on scraps of the actual paper I'll be using.  I'll then keep this beside the picture throughout the process for reference.  Once I have the swatches, I'll whittle them down to a dozen or so colors and place those colored pencils into a working tray.  Sometimes I use an empty Prismacolor tin as my pencil caddy.

Here's a scan of my swatches for this piece.  They're organized by color groups, and within each color group by values.  It's also nice to see all of the colors together to get a feeling of the overall color harmony.  I'll post more work in progress pics as the piece moves along.
