Each complexion has its own specific colour. Apart from the differences of race and ethnic origin, there are some nuances that often occur in almost every type. Here an example of a model with white hair and a ruddy complexion.
1. Often on the temple the local colour has ocher accents.
2. High lights have their own character. Not just a lighter version of the general colour. Here is blue /crimson / white because of the daylight coming in through the skylight in my studio.
3. In this lighting the shadow in the ear is often pure red. Light passes through this blood-filled part.
4. On the cheeks often there are madder lake / crimson hues. Also on the nose. But be careful with crimson, often cadmium red deep / white combination is the solution.
5. On the chin is often blue /grey and certainly in this portrait where I exaggerated the reflected bluish light of the shirt.
Note also the glasses and beard. It’s always a challenge to describe with the fewest brush strokes possible to increase the painterly quality of the image. Finally for me a good portrait is all about the eyes. They form the epicenter of the whole painting. I want the full attention to be given to that particular part.
