Title: Ostwald, sRGB and WCGa colours in chromaticity and in chromatic value diagram;
line elements and derivations of achromatic colours for scaling and thresholds

1. Introduction and goals.
2. Ostwald, sRGB, and WCGa colours in the chromaticity diagram (x, y), and in the chromatic value diagram (A2, B2).
3. Simplified colour-difference formulae for scaling and thresholds.
4. Colour difference formulae CIELAB and IECsRGB for scaling,
and LABJNDx and IECsRGBJND for thresholds.
5. Line elements and derivations of achromatic colours for scaling and thresholds.

The following ten pages BEU0 to BEU9 of this chapter
show the content with links to the single figures in up to six formats.
