1. Introduction and goals.
2. Five lightness and tristimulus value ranges
between black N and white W.
3. delta L*N to L*W: 22,3_96, 4_96, 8,1_96, 14,4_96, 18_96.
4. delta YN to YW: 3,6_90, 0,4_90, 0,9_90, 1,8_90, 2,5_90.
5. with regularity index g* according to ISO/IEC 15775:2022, annex G.
6. Discussion of gamma values for different ranges.
