Section 2, Chapter D
Colour Appearance, Elementary Colours, and Metrics (2022), Image part DEGS

Title: Colour metrics for light and colour as function of the relative luminance L/Lu (Lu=surround luminance)
Experimental data and model function Qab(xr).
1. Introduction and goals.
2. Experimental data from a book for xr=log(L/Lu);
3. Response functions Q/Fab[e^(xr/a) or 10^(xr/a')] with a'=a ln(10).
4. Deviations of the response functions for luminance discrimination.

The following ten pages DEG0 to DEG9 of this chapter
show the content with links to the single figures in up to six formats.
