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

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 BEC5L0NP.PDF, see
BEC5L0N1. PS / TXT / PDF / jpg

BEC5: 6 Ostwald optimal colours
for 8 illuminants Dxx, CIE-02-degree observer, chromaticity
diagram (x, y), contrast C>=288:1.

Figure 2 shows the Ostwald-optimal colours in the chromaticity
diagram (x, y) for the three colour pairs R-C, Y-B, and G-M, 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 for the CIE standard illuminant D65.
For the download of this figure in the VG-PDF format, see BEC50-1A.PDF.


Figure 3 shows the Ostwald-optimal colours in the chromaticity
diagram (x, y) for the three colour pairs R-C, Y-B, and G-M, 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 for the CIE standard illuminant D65.

Figure 4: Output in format A6 of the file BEC9L0NP.PDF, see
BEC9L0N1. PS / TXT / PDF / jpg

BEC9: 6 Ostwald optimal colours
for 8 illuminants Dxx, CIE-02-degree observer, chromaticity
diagram (x, 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 BEC90-1A.PDF.


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