Change DOS color

SYNTAX 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 below 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 2A = Creates a green background with light bright green text, similar to many of the FTP, telnet, and old BBS console screens.
Valid for a session only
