Coloring Tips
- 1 Shade the monolith: light gray on the left, darker gray on the right to show a shadow.
- 2 Speckle the ground with small dots of tan and brown to make bumpy pebbles.
- 3 Color each backpack a different bright color so the explorers stand out.
- 4 Blend sky blue into white for soft clouds and add a warm yellow glow near the mountains.
