compliment + one half right
Compliment plus a right half and compliment plus a half left (the turtle painting) are my favorite color schemes.
Complimentary colors are any two colors directly across from each other on the color wheel.
Move two spaces left or right for your third color.
The additional colors in the painting are mixed.
and blue are mixed to create the browns in the wren.
The green leaves are mixed with the yellow and blue.
