What color are aspen leaves in the summer?
Color Change Science But most leaves aren’t adding a new look, instead they’re taking off their “masks” of green to expose their true shades. Those bright fall colors are always there, all summer remaining hidden by the green that’s created by chlorophyll production as the tree turns sunlight into food.
Why do some aspen leaves turn orange instead of yellow?

Some red aspen trees shine in this colorful grove in the Eastern Sierra Nevada, California.
How do you identify a quaking aspen?
Aspens can be identified by their smooth, white bark marked by black scars where lower branches are naturally self-pruned. Quaking Aspen leaves are somewhat heart shaped, with finely saw-toothed margins and range in size from 1.25-3″ (3-8 cm) long.

What causes aspen trees to turn yellow?
If so, your tree might be entering the early stages of iron chlorosis, a nutrient deficiency that develops when trees aren’t getting the iron they need from the soil. In the summer (or in spring for severe cases), you’ll see the leaves begin to turn from light green to yellow.
