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

Title: Adjacent and separate colour samples for interval scaling and Gamma calculation;
Evaluation example and evaluation of colour steps of the series N-WRGBCMY and RGBCMY-W with 3 or 5 of 17 steps.
1. Introduction and goals.
2. 3, 5 or 9-step intervall scaling;
3. Advantages and disadvantages of the part and complete scaling;
4. Calculation of visual Gamma for 33 grey steps and of the inverse Gamma;
5. Applications and discussion.
Remarks: For the 3 or 5-step similar scaling see the serie fets.htm.
For the 5 or 9-step similar scaling see the serie feys.htm.
