Colour Spaces, Colour Differences, and Line Elements (2021), Image part CEFS

Title: Colour thresholds and line elements in 10 colour spaces LABJNDu0 to 9
1. Introduction and goals;
2. Modifications LABJNDu0 to 9 of the colour difference formula LABJND according to CIE 230:2019;
3. Corresponding line elements for the experimental contrast Y/(delta Y);
4. Absolute lightness L* (CIE 15) and T* (IEC sRGB) and relative lightness l* and t*;
5. Logarithmic and linear figures for L*, T*, l* and t*;
6. Logarithmic figures for threshold delta Y, sensitivity (delta Y)/Y, and contrast Y/(delta Y);
7. Parameters: A0n=1,5, A1n=sv, A2n=cv*cx, sv=0,0170, cv=0,0058, cx=1,00;
8. Variations cx=0,84, 0,67 und 0,42.
