When I was younger and tougher I painted outside all year long, even in the winter.
The palette of the New Hampshire Woods en plein air painting doesn’t quite reach into the blues, nor does it stretch past orange into red. There is absolutely no purple to be found. The option for a color scheme label is therefore “Limited Analagous”, orange, orange yellow, yellow, yellow green, green, and stretching a bit into blue green. I think the painting would have been stronger had it gone all the way into a few blues to make both the greens and the orange a tad livelier.
