Chapter B: Colour Vision and Colorimetry (2020), Main part BELI

1. Introduction and Goals
This part shows colorimetric properties for the CIE-02-degree observer and antagonistic reflection.

Figure 1: Output in format A6 of the file BEL5L0NP.PDF, see
BEL5L0N1. PS / TXT / PDF / jpg

BEL5: 6 Ostwald optimal colours
for 8 illuminants Dxx, CIE-02-degree observer, chromatic value
diagrams (A, B) & (A1, B1), contrast C>=288:1.

Figure 2 shows the Ostwald-optimal colours in the chromatic value
diagrams (A, B) & (A1, B1) for the color pair Y-B, and for the contrast step C>=288 in red.

The table and the figure include important CIE data
for the three colour pairs R-C, Y-B, and G-M
, and for the CIE standard illuminant D65.
For the download of this figure in the VG-PDF format, see BEL50-1A.PDF.


Figure 3 shows the Ostwald-optimal colours in the chromatic value
diagrams (A, B) & (A1, B1) for the color pair R-C, and for the contrast step C>=288 in red.

The table and the figure include important CIE data
for the three colour pairs R-C, Y-B, and G-M
, and for the CIE standard illuminant D65.

BEL9: 6 Ostwald optimal colours
for 8 illuminants Dxx, CIE-02-degree observer, chromatic value
diagram (CAB,2, Y), contrast C=2:1.

Figure 5 shows similar data compared to Figure 2 (in dashed red),
now for the lowest contrast step C=2:1 in green.

For the download of this figure in the VG-PDF format, see BEL90-1A.PDF.


Figure 6 shows similar data compared to Figure 3 (in dashed red),
now for the lowest contrast step C=2:1 in green.
