For this exercise we started with black charcoal and then worked with grays and neutrals. I tend to be so enamoured by HUE, that I don't notice what is darker or lighter.
"Pastels have a wonderful dreamy quality," which implies that hard sharp edges aren't always required.

My second attempt with color. During the class I couldn't see how my colors weren't as dark or as light as the reference image (and I wasn't sure how much I wanted to copy, anyway). Plus, it turns out "they" are right: you can never have too many colors of pastels to choose from. I wish I'd had an even darker purple/blue/maroon for the shady side of the barn. And a softer lighter orange for the light side of the barn.
