Section 2, Chapter B
Colour vision and Colorimetry (2020), Image part BEJS

Title: Ostwald optimal colours for the CIE-2-degree observer;
for 8 Planck-illuminants Pxx, and for 8 daylight illuminants Dxx;
for two complementary hue planes in diagrams (CAB, Y);
for chromatic values CAB and tristimulus values Y;
diffferent Y-tranfers and Y-scales for four contrast steps C=25:1, 10:1, 4:1, and 2:1
1. Introduction and goals.
2. Approximately equal chromatic value CAB in any hue plane.
3. Equal decreasing of chromatic values CAB
for each of the four contrast steps C=25:1, 10:1, 4:1, and 2:1.
4. Reason of the different Y-transfers and Y-scales for the four contrast steps C and discussion.
