Artistic Polar Bear Challenge: 100 Ways In 100 Days. #68 - Adjacent Complementary Tetrad

Today we get to add a fourth hue to our color scheme.  This scheme uses two sets of complements that are next to each other on the color wheel.

The complement sets used in this study are yellow and violet, and yellow-green and red-violet.

Adjacent Complementary Tetrad Bear

Meh.  Maybe not the best color combination for this guy, but it's my first try using this tetrad.  It bears experimentation later on.
