Title: Special colourimetric properties of colour-image technonoly compared to TUBsRGB 2025
Calculations with colour-difference formulae LABJND, CIELAB, IECsRGB, TUBsRGB, and HAULAB
1. Introduction and goals.
2. Special colourimetric properties of colour-image technology;
3. Calculations with colour-difference formulae a. LABJND according to CIE 230:2019;
b. CIELAB according to (ISO/CIE 11664-4);
c. IECsRGB according to (IEC 61966-2-1);
d. TUBsRGB 2025, see https://colour.li.tu-berlin.de;
e. HAULAB 1980: 4 adaptation luminances L=300, 1000, 200, 40 cd/m^2;
f. HAULAB 1980: 4 viewing angles phi=120', 60', 30', 20';
4. Calculation of log and lin [lightness L*, treshold delta_Y,
sensitivity delta_Y/Y, contrast Y/delta_Y]#w";
6. Application and discussion.
