Windows Color command
On Windows (at least Windows 10) you can use the color command at a cmd prompt to change the foreground and background color of the console.
The default color scheme of the cmd console is color 07, but if I want to flip to a black on white I can do:
color F0
Here is the help (found by color /?):
Sets the default console foreground and background colors.
COLOR [attr]
attr Specifies color attribute of console output
Color attributes are specified by TWO hex digits — the first corresponds to the background; the second the foreground. Each digit can be any of the following values:
0 = Black 8 = Gray
1 = Blue 9 = Light Blue
2 = Green A = Light Green
3 = Aqua B = Light Aqua
4 = Red C = Light Red
5 = Purple D = Light Purple
6 = Yellow E = Light Yellow
7 = White F = Bright White
If no argument is given, this command restores the color to what it was when CMD.EXE started. This value either comes from the current console window, the /T command line switch or from the DefaultColor registry value.
The COLOR command sets ERRORLEVEL to 1 if an attempt is made to execute the COLOR command with a foreground and background color that are the same.
Example: "COLOR fc" produces light red on bright white
