The meaning of blue: color temperature on a snowy day
“Lewis R. French raising her sails,” by Carol L. Douglas
I’m busy finishing plein air work from last season. Some of this needs nothing more than a few brush-strokes and a signature, some of it returned home as nothing more than color notes that need to be fleshed out into a painting.
That was the case with this small painting of the Lewis R. Frenchraising her sails at Pulpit Harbor. I started this in the early morning, knowing I had only a few minutes to finish before the American Eagle sailed out. I probably did fewer than twenty brush strokes on site, but Sue Baines of the Kelpie Gallery saw something in it and urged me to finish it.
Normally, I trust my plein air sketches for color notes. In this case what I’d recorded didn’t match my emotional memory of the day, which told me that this had happened just after sunrise. So I heated up the lighting structure and it much more closely resembles the mood of that early morning in Pulpit Harbor.
“Doe drinking in the woods,” by Carol L. Douglas

I painted Doe drinking in the Woods years ago. It was a demonstration to my students on how the color of light works in practice. The setting and lighting were imaginary.
The photograph of footprints in the ice on a winter evening, above, clearly shows blue shadows across the snow. I think it also gives a sense of my frustration about the condition of the sidewalks.
The exception to the color-of-light rule happens in indirect light. There are many places where an ambient cloudy milkiness is the dominant weather condition. In it, both color temperature and contrast are muted.

A snowstorm is an exaggeration of indirect light. There are no shadows; there are merely objects in space. A snowstorm exaggerates atmospheric perspective, too, rendering even middle-distance objects indistinct and neutral.
Artists constantly check themselves against a construct called “color temperature.” There are warm and cool colors, and warm and cool variations within each color. A warm color gives us a sense of warmth and energy and tends to draw our eye, like the life preserver on my painting of the Cadet. A cool color recedes from the eye and gives us a sense of static coldness, like the underside of Rockwell Kent’s iceberg from yesterday.
I’ve written before about the color of light, and it’s one of the most important concepts in painting. The earth’s atmosphere bends light just like a prism does, so what you see is always tinted. Either the light is warm and its shadows cool, or the light is cool and its shadows warm. Which that is depends on the time of day and the season of the year.
In the wintertime, the sun barely crests the treetops here in the North. The ground is often covered with neutral white snow. That gives us textbook conditions to see light temperature in action, for the sun on the horizon always gives us warm light and cool shadows.
