Section 2, Chapter E
Colour Metrics, Differences, and Appearance (2023), Image part eefs

Title: Relative linear colorimetric variables
as logarithmic and linear function of Y;
lightness, Y-differenz, sensitivity and contrast;
colour spaces CIELAB and TUBJND, see CIE 230
1. Introduction and goals.
2. Equally spaced grey series 3,6 < Y < 90 for four display reflections
Yref=0,4, 90, 1,8 and 3,6 with regularity index
g* according to ISO/IEC 15775:2022.
3. Relative lightness L*/L*u.
4. Relative Y-differenz delta_Y/delta_Yu.
5. Relative sensitivity (delta_Y/Y)/(delta_Yu/Yu).
6. Relative contrast (Y/delta_Y)/(Yu/delta_Yu).
7. Discussion of results for colour vision.

The following ten pages eef0 to eef9 of this chapter
show the content with links to the single figures in up to six formats.
