Online Class: Color Study of Autumn Leaves in Watercolor
Registration required. Space is limited. Please email contact@gokm.org or call 505-946-1000 for assistance with registration.
Inspired by Georgia O’Keeffe’s close-up paintings of fall leaves, this class will provide a focused practice of color study by capturing autumn hues in watercolor.
A longtime educator of color theory for artists and designers, teaching artist Sudeshna Sentupta will share her professional paint-mixing concepts based on the position of paints in a color wheel that uses cyan, magenta, and yellow primaries.
Participants are welcome to gather fall leaves for inspiration during the class, or they can follow along with the in-class painting demonstration to create their autumnal color swatches.
