Section 2, Chapter F
Colour metrics for chromatic and luminance adaptation (2024), Image part febs

Title: Spectral sensitivity and saturation;
line elements, responses and discrimination as function of luminance;
comparison of CIEXYZ and HPE-LMS spectral values with model functions;
antagonistic achromatic and chromatic responses as function of luminance;
spectal definition and discrimination of Ostwald colours.
1. Introduction and goals.
2. Complementary antagonistic symmetric responses and saturation.
3. Antagonistic achromatic and chromatic responses as function of luminance.
4. Colour vision and physiological responses in the range of surface colours.
5. Comparison of CIEXYZ and HPE-LMS spectral values with Gauß-model functions 6. Antagonistic spectral Gauß-colour values and responses.
7. Spectal definition and discrimination of Ostwald colours.
for further information and discussion, see febi.
