Section 2, Chapter G
Equally spaced colour scales for optimal colour-image quality (2025), Image part gejs

Title: Adjacent and separate colour samples for interval scaling;
Evaluation example of colour steps of the series NCMY-W with 5 or 9 of 17 steps; Three surrounds mean Grey U=N08w, dark Grey D=N04w, light Grey H=N12w
1. Introduction and goals.
2. 5 or 9-step intervall scaling;
3. Evaluation example of the head room with 5 samples on surround N and U;
4. Applications of greyish and luminous colours and discussion.
Remark: For the 5 or 9-step similar scaling of the series
NCMY-W, see the series gefs.htm.
