three rings of red ink

Page 11 of the orange → royal purple → void run: marking pages 1–10.

READINGThe judgements are mine; the score is computed from the table. The pages sit on three nested rings: low severity in the orange core, moderate in the purple shell, serious out in the void.

Across the run

Works. Real CIE colour matching arrived. All nine colour pages share one CIE 1931 2° table (CVRL data, 5 nm, checked: ȳ(555) = 1, x̄(600) = 1.0622) and one dominant-wavelength routine, so "spectral vs non-spectral" is computed, not asserted. The nesting thesis was tested and held: orange has a dominant wavelength, purple mixtures land on the line of purples. Two premises were corrected rather than echoed. Friedländer's yield is 12,000 snails per 1.4 g (≈8,600 per gram), not per gram. And potassium lilac is only a borderline purple, because the eye barely registers the 766/770 nm pair.

Weak. Several spectra are hand-placed Gaussians (the aurora altitude profiles and the leaf pigment bands), and the aurora's pink lower edge uses stand-in lines (670 and 410 nm) rather than the real N₂ first-positive bands. The white-point rescale on Cosmic Latte is done in sRGB, not a proper Bradford/CAT02 transform. Perkin's crowd and the GRS shrink curve are invented or interpolated between two points.

Unverified. The cobalt-glass transmission (0.05% of yellow) and the anthocyanin band position versus pH were chosen by eye, as was the Hering/LGN history line on the opponent page. The Great Red Spot's 1830 start of continuous monitoring is NASA's wording, and the earlier 1665 sightings are not used.

Next time. Use the real N₂ 1PG band and a measured auroral spectrum; the CAT02 chromatic adaptation; measured β-carotene and cyanidin absorption spectra; and the 2dF cosmic spectrum itself (Baldry et al. 2002) instead of a blackbody toy.
