Reconstructed gradient

The gradient distilled from the scene, unrolled left to right by stop; the authored angle is 180° (used by the hero and exports), while gallery cards share a uniform 135° sweep.

Why it works

Chroma in the blue-violet half is paid for in lightness. Same family of blue, same clear day, same 210°–270° window: Yashiori's most chromatic 3% sits at L 0.53 with chroma 0.137, while Kannazuka in Hazy Daylight manages only 0.122 at L 0.63. The two blue bands peak at almost the same height (0.182 against 0.177) — the difference is not how rich they could get, but whether they were willing to go dark for it. This frame was, which is why its sky is deep, and why it is the most convincingly noon of the four.

Take the sky one step deeper and the whole picture follows

The sky along the top edge measures L 0.48, chroma 0.132, hue 254°. Take the same upper edge in Kannazuka in Hazy Daylight and it is L 0.68, chroma 0.110, 240°. The two blue bands peak within 0.005 of each other (0.182 against 0.177), yet the means actually collected differ by 0.022 — because Yashiori was willing to put its sky at L 0.48 and Kannazuka stopped at 0.68. If a palette must get richer without changing hue, lower the lightness; saturation will not produce it. The ceiling is fixed, and in bright territory it sits very low.

The cliff that reads as sandstone is a 238° blue

The great cliff across the middle ground looks like tan sandstone; it measures L 0.54, chroma 0.055, hue 238° — 42% of the sky overhead. The strand below that reads as yellow sand is L 0.73, chroma 0.056, hue 182°, and a 330°–90° search over the same rectangle returns nothing matched. Across the whole frame that warm window holds 84 pixels (0.009%) at a mean chroma of 0.029. Narukami Island in Clear Haze measured the same effect — cliff 244°/0.065 against sky 245°/0.110, hue identical, four tenths of the chroma cut away. Here 58% is cut and the hue gives up another 16°. The same law, pushed further because the sky it is measured against is deeper.

Ninety-eight pixels of maple out-saturate the whole sea

One red-leafed tree stands on the clifftop toward the right. The 315°–345° window holds 98 pixels in the entire frame, averaging L 0.71, chroma 0.111, hue 319°, peaking at 0.152. In the same picture the sea, at a comparable L 0.74, reaches only chroma 0.077, and the blue band covering 87.81% averages 0.092. At around L 0.7 blue has long since hit its ceiling while rose still has 0.111 to spend — that is the whole difference between an expensive hue and a cheap one. If you want real chroma at high lightness, do not ask blue or violet for it; ask rose, cyan, or green.
