No odd symbolism here, just a cinder/blackboard colored unicorness. :-)
Since I keep losing control of color saturation I'll be working for a while with a restricted palette based on earths: titanium white, ivory black, natural sienna, burnt sienna, yellow ochre and ultramarine. This painting is done using with this palette. It's a very simple palette which forces to pull the most out of each color and to think of color temperatures rather than hues, which is the key to controlling saturation.
