Kai and Gerda are enjoying a peaceful moment together on the docks near the river. Kai has his head bent, looking attentively at the book he is holding. Gerda is standing beside him, her eyes also focused on the book. They both have a peaceful and content expression, their heads close together. The colors around them should be rich and warm; a light golden yellow for the docks, a tranquil turquoise for the river, a deep forest green for the trees in the background, and a soft dusty pink for their faces. Gerda's hair could be a warm brown, like freshly-brewed tea, while Kai's would be a deep chocolate. Whatever colors you choose, their faces should be illuminated and inviting, soft but with depth. The feelings of peace and friendship should be unmistakable.
