In this coloring page, the quail are all lined up, with four of them standing on the ground and two of them taking flight. I would start by coloring their bodies a deep brown, and then filling in the white stripes on each of their wings with a lighter shade of brown. You could use some gray or even a light yellow to create highlights on the feathers. The ground below the quail could be colored light green, with darker green spots in the grass to add some depth. For the sky, you could use bright blues and oranges to show off a setting sun. Additionally, you could use black to outline each quail for more definition and contrast. No matter how you decide to color the page, it will be sure to look beautiful when you're done!
