Title: Ostwald optimal colours as surface-colour reference;
Tristimulus values Yu for equal greyness;
Antagonistic receptor functions Fab and derivation F'ab;
Fab as eponential functions of the relative luminance and the contrast.
1. Introduction and goals.
2. Ostwald optimal colours as surface-colour reference.
3. Tristimulus values Yu for equal greyness as function of (x,y);
4. Antagonistic receptor functions Fab and derivation F'ab.
5. Fab as exponential functions e^x and 10^x with the relative luminance x=log(L/Lu).
6. Fab and F'ab as function of the contrast C=Lw:Ln.
