The color attribute is specified by two hexadecimal digits-the first is the background and the second is the foreground. Each number can be one of any of the following values:
0 = Black 8 = Gray
1 = Blue 9 = light Blue
2 = green A = Light green//Case insensitive
3 = Lake Blue B = Light Green
4 = Red C = Light Red
5 = Purple D = Lavender
6 =xxxe = Light XXX
7 = White F = Bright White

Example: Color FC
If no parameters are given, the command restores the color to CMD. The color at which EXE starts. This value is from the current console window, the/T switch, or the DefaultColor registry value. If you use the same foreground and background color to execute the color command, the color command sets ERRORLEVEL to 1

if/i "%choice%" = = "2" goto Setsave
if/i "%choice%" = = "3" goto Kaiji
if/i "%choice%" = = "4" goto clean
if/i "%choice%" = = "Q" goto ENDD
