Here are 3 rough photoshop studies I completed with my little Wacom Tablet that demonstrate some of the color chroma concepts I wrote about earlier this week. They really show clear color gradations. I hoped this might apply the idea creatively and also be a little more interesting than the cubes.
The first (just below) was a study I referenced and caricatured from a Dean Cornwall painting that was posted over at the Gurney Journey. I loved the color and key of the painting so much, I had to investigate. You can see the bleaching effect best in his white shirt sleeves where the shadows have more chroma than the light side. More subtly you can see where his beard is slightly more brown in the mid-tone before the light's begin.
In the digital study of the face above is lit from above by low red-orange light. For the lightest lights I used the most saturated orange I could find. In the two brightest highlights (in the nose and top of the head) I added white to lighten them further so they would punctuate the form stand out beyond the rest.
In this last invented face and lighting scheme, you can see the flesh tone graying toward the dark side and intensifying toward an orange in the light side. The man's shirt goes through the same gradation.
