Adjusting Color to Match Observation

We start with a selected color. Then we analyze what is needed to match what is observed, and make the necessary adjustments...

The shadow on the throat is deep and dark. We start with Dark 2. To increase the intensity and the warmth, we add Alizarin Crimson and Burnt Sienna. To push it down in value still more, we add a bit of Burnt Umber.
The halftone on the upper lip is a complex color that is greyed and cool. We start with Halftone 1. To make it darker, we add Dark 1. To make the mixture cooler, we add Chromium Oxide Green.
The dark halftone on the side of the nose and the nostril is warm and intense. We start with Halftone 2, but the warmth and the intensity need to be stepped up. We achieve both with touches of Venetian Red and Cadmium Orange.









Now we want to mix the cooler pinkish color on the edge of the forehead to the left of the highlight. Again we start with Light 3. We need to go cooler and lighter. We achieve cooler by adding a touch of Alizarin Crimson. We make the mixture lighter by adding White.














 

 

 

The rich shadow color is Dark 1 deepened with Chromium Oxide Green.
Our goal is mix the warm color on the forehead. We select Light 3, which must be made warmer, darker, and more intense. We go darker by adding Halftone 2, and warmer and more intense by adding Cadmium Orange and a tiny touch of Cadmium Red Light.
