Pure color in reflected light
 

I like to "get away" with adding intense pure color into reflected light. I define "pure color" as a color without the addition of white. The light under Whitney's chin, nose and lower lip is reflected light and is pure cadmium orange + yellow ochre. Despite the bright color, it is not really noticeable unless you're looking for it.

Pure color can be a good approach to consider here. If you lighten an area of reflected light too much with white, you run the risk of fragmenting a solid shadow.

Although the accepted knowlege is that "reflected light" is actually reflected from a color specific object nearby, I don't pay much attention to this. I say that whatever color looks good and you can get away with...do it!

Halle has a brushstroke of Cadmium Orange + Indian Red in the reflected light under the nose and chin.

"Mother and Child" has Cadmium orange in the reflected light under the mother's chin, under the baby's nose, arm, and bottom of drapery.

Are those specific colors applied opaquely or semi transparent (glazing)?

Were these lovely paintings painted with the Gensis paints?

No, these paintings were done with traditional oil paint. -Karin
