I use the Windows command prompt on a daily basis. Done so for decades. Whether I'm pinging 8.8.8.8 or finding a default gateway, the command prompt is a trusty companion. I never knew until today that you could change its entire look with eight characters. Next time you find yourself in that dreary old screen, type color ?.
The first hex character changes the background color and the second hex character changes the text color.
As you can see in the screenshot above, color f0 inverts the default command line.
