Gouache Painting

This is a gouache still life painting using a monochromatic color scheme.  A monochromatic color scheme has one color and all its tints (adding white), shades (adding black), and tones (adding gray).
At the side you can see three strips where I painted different tints/shades/tones of blue, which were then used in the actual painting.
Like in the drawing unit, the process began with rendering out the shape and doing the outer contour line.  Light and dark placement was done with the lightest tint and darkest shade, for highlights and shadows.  The rest of the mixed colors were used for other parts.
I chose blue because I thought its tints/shades/tones would look nice, but it ended up being a challenge for the actual still life part.  My original object was red, so I had to translate the red I was seeing into a vague idea of how bright or how saturated the color was.  Tones of blue were used around the edges of the "sections" to help separate them.
