This is an autumn scene with the trees shifting towards the deep tones of Autumn. They are adorned with the orange and yellow leaves that crunch beneath our feet as we walk. The people gathering the leaves in the foreground are busy raking them up from the grass into large piles waiting to be collected in bags. To color this image, I would use browns and oranges to depict the changing leaves, focusing on more muted warm tones for the deeper shadows. To give a hint of the chill in the air, I would add cooler purples and blues for the distant trees, and possibly a few flashes of yellow and orange to denote the last of the summer heat. With the background, I would use warmer browns transitioning to the heavy greens of winter. For the people, I would suggest lighter, brighter colors like pinks and blues that stand out against the Autumn hues.
