A wheel becomes a solid
Hue goes around
Red, yellow, green, blue, and purple wrap around the central gray axis. Each hue has its own vertical page.
Value goes up
Dark colors sit low; light colors sit high. Colors at the same height share a Munsell value, even when their hues differ.
Chroma goes out
Gray is at the center. Color strength increases with distance from it. Every hue uses the same chroma scale, so the outer edge is uneven.
What this model represents
The points use the 956 renotation coordinates for colors in the 1929 Munsell Book of Color, published by the Rochester Institute of Technology. They are reference coordinates, not new measurements of those physical chips. Connecting outlines trace the extent of this sample set, not a universal limit on visible colors or modern pigments.
The published samples occupy values 2–8. The gray axis extends conceptually from 0 (black) to 10 (white). Hue is angular position, chroma is radial distance, and value is height; the relative vertical and horizontal drawing scales are chosen for legibility. Empty positions mean no sample in this dataset, not that a color is impossible.
Display colors are converted from the source CIE xyY coordinates, with the historical Y scale corrected by 0.975 and Bradford adaptation from illuminant C to D65, then encoded as sRGB. Some samples exceed sRGB and are clipped for display; their positions remain unchanged. Sample colors have no simulated lighting or shading. Your screen and surroundings still affect their appearance.
This is a map of color appearances, not a paint-mixing simulator. A map of your palette would require measured swatches and mixtures under specified lighting.
