Title: Special colourimetric properties of colour-image technology
Calculations with colour-difference formulae LABJND, CIELAB, IECsRGB, and TUBsRGB
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;
4. Calculation of log and lin [lightness L*, treshold delta_Y,
sensitivity delta_Y/Y, contrast Y/delta_Y]#w";
6. Application and discussion.
