In this coloring page, a beautiful and majestic dark brown horse stands peacefully in a pasture, surrounded by tall grass and wildflowers. The horse has a thick coat of fur, a long mane and tail that flows behind him. He is looking intently at the camera, as if curious as to what the viewer thinks of him. To bring out the details of the horse, try using lighter shades of brown for his fur, perhaps adding flecks of golds. The mane and tail could be set off with bright blues and purples to give them a lush, vibrant look. To make the scene brighter, use a yellowish green for the grass and some cheerful shades of pink and purple for the flowers blooming around the tree and horse.
