推荐答案
如果你已经知道的颜色与名称的列表，你可以看到它的那些已知的颜色给定的目标颜色是'最接近'来，用亲近沿线的函数（F＃code）：
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
无论已知的颜色之一具有最小差异，以要名的目标颜色，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.
