Stick to Your Values
The dictionary says...
"Core values are the guiding principles that dictate behavior and action."
As an artist the concepts of value and color guide my palette choices. I try to always begin a painting with a small value study such as this one for "Tangled Up in Blue". (The tick marks guide me when I transfer my composition to my painting surface.)
I take a photo of the painting and use the mono filter to change it to a black and white version of the painting.
Stick to your values in life and in painting!
