- **Ground:** grey-green. - **First marks (330–560):** **cream** cloud ovals, a **Prussian-blue** dab at the very top, **dark teal** verticals at the lower right (pines), and warm tan at the lower left (the foreground rock). - **About frame 700:** a blue sky band, cream cloud bars, grey and tan granite masses, and a **dark diagonal pine** from the left. - **About frame 860:** **Half Dome's sheer cut face** at the centre right, blue-grey ridges, a gnarled pine framing the top left, a warm sandstone boulder in the foreground, and a rust-orange streak on the cliff. - **Refinement (985–1385):** the sky deepens to **Prussian blue at the top and fades lighter toward the horizon**, like a print gradation. The cloud bands become crisp horizontal bars, and the pine at the top left turns from a soft mass into crisp, tapering branch and needle strokes (clearest 1240–1340). - **Touches:** a warm gold mark lands on the sunlit far ridge at the right at frame 1546 (x 0.85, y 0.56 from top). The old touch narration (the sky gradation) now plays in the refine deep dive, where the gradation actually happens.
