List out the universal colour code.

The ISCC-NBS Method identifies 267 blocks of colors. Each block is given a color name devised using a set of adjectives and suffixes. Each color block defines a range of colors--not a single color--that have the same name. This range of color in each block is an acknowledged disadvantage, but it is pointed out (COLOR, p. 4) that a set of 267 color names is analogous to calendar dates for chronological events. This method is suitable for "a variety of scientific and industrial applications" (COLOR, p. A-13). The UCL at levels above 3 defines finer divisions of colors with no names, rising to approximately five million divisions in UCL Level 6. COLOR also lists color names from various sources for each UCL Level 3 color block (pp. 37-82) and a Dictionary of Color Names which lists thousands of color names and their corresponding UCL Level 3 block(s) (pp. 85-158).
The color blocks of the UCL Level 3 are defined using the Munsell System of color which describes the hue, value, and chroma of colors. I prepared this page using Munsell Renotation Data from the Munsell Color Science Laboratory, Rochester Institute of Technology. This data was converted to hexadecimal using formulas given by Easy RGB, and the colors were named according to COLOR, pp. 16-31. Up to 6 swatches per color name were chosen to represent the range of colors in each block. Where fewer than 6 colors are shown, fewer than 6 samples of color were available in that block range in the data.
The block number is given for each of the 267 UCL Level 3 color names. Color swatches are defined by using the hexadecimal code for the color. The swatch shows the Munsell notation for the color in the form Hue Value/Chroma above the hexadecimal code. I was not able to find samples of color for Munsell chroma values under 2, so these color blocks have "No samples available." Remember: each of these 267 color names do not each identify a single color, but a range of colors.
