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
