five rings of red ink ·

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

READINGThe judgements are mine; the score is computed from the table. The pages sit on five nested rings: minor marks in the orange core, moderate in the purple, serious out in the green; the yellow ring and void stay empty for what was left out.

Across the run

Works. The five-layer sequence is computed, not asserted. Orange, green and 580 nm yellow are spectral, purple is not, and the yellow ring can be swapped for a 630+532 nm mixture that lands on exactly the same dominant wavelength (a metamer). The last critique's "real refraction" item is done: the White Sun uses Bennett's horizon refraction (34.5′) with Edlén dispersion, Rayleigh extinction and Kasten–Young airmass, all Bradford-adapted. Bilirubin uses a measured spectrum. Firefly, chrome yellow, yellowcake and the Sun's 5772 K are sourced to primary or agency documents.

Weak. The Mars and Saturn reflectances are invented smooth curves; their self-checks only confirm the shapes I chose, which is circular. Gold and chrome yellow are logistic edges. Io's and yellowcake's colours are palette, not CIE. The opponent page's unique-yellow range and Hunt–Pointer–Estévez model are textbook simplifications.

Unverified. Silver's 3.9 eV edge; Io's surface gravity (1.796 m/s², used from memory); the 575–580 nm unique-yellow range. Not addressed from last time: in-vivo leaf data, a measured uranium-glass spectrum, copper molecular bands.

Next time. Measured planetary reflectance spectra (e.g. telescopic Mars and Saturn albedo spectra); a measured gold/silver reflectance table (Johnson & Christy 1972); the Stockman–Sharpe cone fundamentals instead of HPE; and the three left-over items above.
