Secondary Color Scheme

Ledger book drawing by Howling Wolf.   I selected this piece of work due to its main use of secondary colors.  The color orange dominates the drawing. On the color wheel orange is combination of red and yellow.  Except for black and blue there are no other primary colors used in the drawing.  The drawing looks as if if were created by crayon which does a wider variety of colors to choose from other than the basic primary, secondary and intermediate colors.  The piece is very complex in the details.  The use of orange grabbed my focus not only on the tapestry but also the much larger than life horse.
