Changing the DOS Background Colour

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 )

goto

[HKEY_CURRENT_USER\Software\Microsoft\Command Processor]

You ‘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

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.
