Abstract
Early rendering algorithms relied exclusively on three-dimensional spaces for color computation, such as RGB and CIE XYZ. Recent rendering advances use full spectral information for illuminants and surfaces, resulting in much greater accuracy and realism. These expensive computations can be wasted, however, if ad hoc methods are used to adjust the final image on the monitor, in film, or in print. Ineficiency and inaccuracy can be avoided with some knowledge of device gamuts and color reproduction algorithms. This course follows spectral data through the graphics pipeline, examining issues of rendering, color science, perception, gamut mapping, and color management. We conclude with a discussion of trends and open problems in managing spectral data for accurate color reproduction. Participants will learn not only the theoretical background of color and spectral reproduction, but practical guidelines often omitted in technical papers.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
