The following ten pages BEQ0 to BEQ9 of this chapter
show the content with links to the single figures in up to six formats.

Title: Ostwald optimal colours for the CIE-10-degree observer;
for 8 Planck-illuminants Pxx, and for 8 daylight illuminants Dxx;
for two complementary hue planes in diagrams (CAB2, Y);
for chromatic values CAB and tristimulus values Y
1. Introduction and goals.
2. Approximately equal chromatic value CAB2 in any hue plane.
3. Equal decreasing of chromatic values CAB2
for each if the four contrast steps C=25:1, 10:1, 4:1, and 2:1.
4. Reason of Y-transfer for four contrast steps C and discussion.
