The scene is a peaceful and wild one. The river rushes strongly, creating a tumultuous whirlpool of activity. The large rocks that jut out through the rapids are like a natural obstacle course, with their jagged edges just barely peeking through the turbulent waters. The sky is an oppressive, cloudy grey that creates a cool, dark atmosphere. When it comes to colouring this scene, there are many options. The sky, rocks, and even the river could be a variety of beautiful blues, greens or browns. The white rapids could be highlighted with vibrant yellows and oranges, while the cooler shades of grey provide a nice contrast.
