I went looking for the names of the "216 non-dithering colours" that seem to have become standard internet use these days. Whilst there's only 216 to choose from here, I must admit that their names are not nearly so interesting as "belly o' the fawn" or "sigh of violets" , or even "marone".

However, if you are iterested, you could try and guess which colour is closest to the chart. Which, for example, would be "eau de nil" to you?

(warning- different browsers DO show these colours slightly differently)
