Color Wheel Catalog
The 12-hue traditional RYB artist's wheel plus the 6-hue additive RGB light wheel — 18 named positions, each with its role (primary / secondary / tertiary), schematic sRGB value, and the parent hues it mixes from. Every row and every swatch below is computed live at build time from OnlyCSharp.Data.Catalogs.ComputerGraphics.Color.ColorWheelCatalog. Authored as .razor; rendered to static HTML.
Source: traditional color theory (J. Itten, The Art of Color, 1961) and additive RGB primaries (CIE/IEC). Didactic/schematic values — see the leaf README.
