Reading the Munsell hue names
Go around the wheel and the labels alternate between five main color families and the colors between them: R, YR, Y, GY, G, BG, B, PB, P, RP. Red, yellow-red, yellow, green-yellow, green, blue-green, blue, purple-blue, purple, red-purple. Then back to red.
That tells you the hue, but not the whole color. A pale pink and a deep red can share a hue family. Munsell uses value for how light a color is and chroma for how far it is from a neutral gray. You need all three to specify a color.
This page only shows the families. There are no controls, and the wedges are ordinary HSL fills in an SVG, rotated 36 degrees at a time. They aren't measured Munsell samples. Even their HSL lightness values don't guarantee equal perceived lightness, so this wheel won't give you a reliable paint match.
The Munsell notation guide shows how the full notation fits together. To move through lightness and chroma on screen, there's also an interactive 3D explorer. That one uses OKLCH, a different color system, despite living alongside these Munsell experiments.
