The coloring page shows three minions enjoying a peaceful day by the stream. One of the minions is standing on a large rock in the middle of the stream, holding a fishing rod up in the air while they fish. The other two minions are sitting on the grassy bank, one of them with a fishing rod in its hand and the other tearing apart a freshly caught fish. The whole scene is set against a backdrop of rolling hills, tall trees and an inviting blue sky.
To color this picture, I would start with a light green for the grassy bank, followed by a deep navy blue for the streams. I would use shades of grey for the rocks in the stream. The minions would of course be colored yellow. The sky can be filled with a blend of light blues and whites for a pleasing gradient. To add more depth and detail, consider adding some pink streaks near the horizon for a nice sunset feel or a light dusting of grass blades or other details in the foliage. Finally, shades of green and brown can be used for the trees and hills in the background.
