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

Title: Ostwald-optimal colours for the CIE-10-degree observer;
for 8 Planck-illuminants Pxx, and for 8 daylight illuminants Dxx;
for complementary optimal colours of antagonistic tristimulues values X10, Y10, Z10, and
Xw10-X10, Yw10-Y10, Zw10-Z10 in the CIE chromaticity diagram (x10, y10);
for four contrast steps C=25:1, 10:1, 4:1, and 2:1
1. Introduction and goals.
2. Location of complementary Ostwald-optimal colours in the CIE (x10, y10) chromaticity diagram.
2. Approximately equal chromatic values CAB2,10 for all Ostwald-optimal colours.
3. Decreasing of chromaticity difference between colour and white
for any of the four contrast steps C=25:1, 10:1, 4:1, and 2:1.
4. Change of the triangle location in (x10, y10) to a circular location
in the chromatic value diagrams (A2,10, B2,10) for any of the four contrast steps C and discussion.

The following ten pages BED0 to BED9 of this chapter
