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

Title: Colour metrics for light and colour as function of the relative luminance L/Lu (Lu=surround luminance)
Experimental data and model functions Fab(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. Derivations of the response functions for luminance discrimination.

The following ten pages DEC0 to DEC9 of this chapter
show the content with links to the single figures in up to six formats.
