Title: Chromatic adaptation model TUBLAB2 and hue threshold,
similar chromatic values of sRGB and Ostwald colours,
HPE transfer between XYZ and LMS(PDT).
1. Introduction and goals.
2. Chromatic adaptation model for eight illuminants Pxx (Planck) and Dxx (Daylight);
3. Similar chromatic values (A2, B2) of the sRGB-display colours, and the Ostwald colours;
4. Hunt-Pointer-Esteves (HPE) transfer between XYZ and LMS(PDT) in both directions;
5. Chromatic adaptation model TUBLAB2, hue threshold dhA2B2=6, eigth illuminants Pxx (Planck) and Dxx (Daylight);
6. Wavelenght limits of 6 Ostwald colours with hue thresholds dhA2B2=6 and 18, contrast C=25:1 and 2:1.

The following ten pages DEV0 to DEV9 of this chapter
show the content with links to the single figures in up to six formats.
