<a href="https://en.wikipedia.org/wiki/sRGB" class="extiw" title="w:sRGB">sRGB</a> approximations of the 1943 <a href="https://en.wikipedia.org/wiki/Munsell_color_system" class="extiw" title="w:Munsell color system">Munsell</a> renotations. The image includes every real color swatch, but the colors have been normalized so they fit within the sRGB <a href="https://en.wikipedia.org/wiki/gamut" class="extiw" title="w:gamut">gamut</a>. Also, due to the simulated lighting, the precise color values are affected even further. Source data is "real.dat" from <a rel="nofollow" class="external text" href="http://www.rit.edu/cos/colorscience/rc_munsell_renotation.php">Munsell Renotation Data</a>. Note that the central gray column does not appear in "real.dat" and was added later. A corner has been cut away so you can see inside the shape.
