The value Default Color controls the foreground and background colors used in command prompt windows. It has a default value  of 0, for standard white text on a black background.

To do this follow the next steps:

1. Open the Registry Editor click on the Start button on your taskbar, then click on Run and type "regedit" and click on OK to start the regedit utility.
    
2. Expand HKEY_CURRENT_USER\Software\Microsoft\Command Processor (see picture 1).

3. You can replace this value with a two-digit hexadecimal number, in which the first digit selects a background color and the second a foreground color. The hexadecimal codes are:
   
   0 Black
   1 Blue
   2 Green
   3 Aqua
   4 Red
   5 Purple
   6 Yellow
   7 White
   8 Gray
   9 Light Blue
   A Light Green
   B Light Aqua
   C Light Red
   D Light Purple
   E Light Yellow
   F Bright White

A value of F0, for example, would give black text on a white background, and 1E would yield yellow text on a blue background.

The change should take effect the next time you open a console window.
