Converting Color to ConsoleColor?

Question

What is the best way to convert a System.Drawing.Color to a similar System.ConsoleColor?

Answer 1

The distinct default "white-on-blue" color of PowerShell.exe before version 6 (and any ConsoleWindowClass window) is actually DarkYellow on DarkMagenta if you check $Host.UI.RawUI. This is because the ConsoleColor enum values are just indices into the console color table, which is configurable (see this answer about DarkYellow).

Here are the hex RGB values for the default console color table:

Value Hex RGB Name
    0 #000000 Black
    1 #000080 DarkBlue
    2 #008000 DarkGreen
    3 #008080 DarkCyan
    4 #800000 DarkRed
    5 #012456 DarkMagenta
    6 #EEEDF0 DarkYellow
    7 #C0C0C0 Gray
    8 #808080 DarkGray
    9 #0000FF Blue
   10 #00FF00 Green
   11 #00FFFF Cyan
   12 #FF0000 Red
   13 #FF00FF Magenta
   14 #FFFF00 Yellow
   15 #FFFFFF White
