推荐答案

如果您有一个带有名称的已知颜色列表，您可以使用 'closeness' 函数(F# 代码):

If you have a list of known colors with names, you can see which of those known colors a given target color is 'closest' to, using a 'closeness' function along the lines of (F# code):

let Diff (c1:Color) (c2:Color) =
    let dr = (c1.R - c2.R) |> int
    let dg = (c1.G - c2.G) |> int
    let db = (c1.B - c2.B) |> int
    dr*dr + dg*dg + db*db

无论哪种已知颜色与您要命名的目标颜色的差异最小，请使用该名称.

Whichever one of the known colors has the smallest diff to the target color you want to name, use that name.
