The value DefaultColor 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.
CHANGING DOS BACKGROUND
Open your registry (press win+r and type regedit , hit enter )
u'll find "DefaultColor"
You can replace it's 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:
Hexadecimal value Color
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.
