Appendix

Every figure, every model.

The colour sections lead with one model in a shared box, because that is how a comparison reads. This page is the other view: each model in its own axes, at full size, for all four boards, plus the all-models grid and the full CIE horseshoe. Nothing here is generated differently from what is published upstream; it is the same render, shown one at a time.

Color Preservation

The delivered file versus what came back, on the CIE 1931 diagram. Both sides are the same 8-bit Rec.709 file, so any separation is colour the model moved.

Tone Preservation

Luminance distribution, delivered file versus return. Both sides are 8-bit, so the histogram is smoothed to show where the brightness moved rather than the quantisation both share.

Gamut Fidelity

The ACES plate versus the return, cropped tight on the Rec.709 boundary where the crossing is decided. The full CIE horseshoe version is below.

Dynamic Range Fidelity

The plate's smooth continuum against the return's comb. Teeth are decimated to a countable number. The envelope is the data, the tooth count is not.

All models, one grid

Every model and the ground-truth control in a common box, drawn as 90% containment regions rather than clouds. Panel 1 is the delivered file against itself, which is the shape a faithful return makes.

The full CIE locus

The same plate-versus-return clouds on the whole CIE 1931 horseshoe, with the Rec.709, AP1 and AP0 boundaries. It is the reference frame a colourist expects, at the cost of the detail the cropped views show.
