Orange You Glad It’s Halloween?
Botanical illustration workshop with colored pencils
🧡🍁
Celebrate Halloween—and the golden colors of fall—at Hoyt Arboretum! In this colorful nature-inspired workshop, we’ll explore the many shades of orange found in autumn leaves, from golden ochre and pumpkin to rust, copper, and deep orangey-reds.
Using colored pencils, you’ll learn simple techniques for layering, blending, shading, and building rich color. We’ll work from a hand-illustrated worksheet of a Bigleaf Maple leaf (Acer macrophyllum), one of the Pacific Northwest’s most spectacular fall trees.
Along the way, we’ll add a little Halloween spirit, looking at how shadows, dramatic color combinations, and unexpected details can give botanical art a slightly mysterious—or even spooky—feeling.
Weather permitting, we’ll spend part of the class in the Hoyt Arboretum classroom and the other half out among the trees, where you’ll choose a fall leaf and practice illustrating it on your own.
Bigleaf Maple worksheet we will use for this class, with demonstration of illustration with layered colored pencils.
No drawing experience necessary. Beginners welcome! A hand-illustrated template will be provided.
This workshop is taught by Molly Chidsey, a Portland-based illustrator with a background in environmental and sustainability advocacy. Workshop host: Hoyt Arboretum Friends.
