This coloring page features a sad cartoon bear. Its head is bowed and its arms limp at its sides, conveying a sense of melancholy. I would color it with an earthy palette, focusing on shades of brown and tan to give the bear a sense of warmth and security. I would add hints of blue and golden ochre to create a subtle contrast and to suggest a fresh, clear air of hope and possibility. The bear's expression could be further enhanced with a bit of shading, emphasizing its sense of dejection. Finally, I would include a few touches of red to capture the emotion and bring a sense of comfort to the viewer.
