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

Title: Colour metrics for light and colour as function of the relative luminance L/Lu (Lu=surround luminance)
Experimental data and model functions Q/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. Deviations of the response functions for luminance discrimination.
5. Antichromatic models of colour vision.
6. Receptor sensitivity for achromatic colours.
7. Logarithmic and linear models for combinations of the sensitivities.
for further information and discussion, see DEAI.

The following ten pages DEA0 to DEA9 of this chapter
show the content with links to the single figures in up to six formats.
