How do you change the background of the texting keyboard to black?

[AC Question]

The keyboard is 3 shades of gray and white. It is very difficult to see the shift characters on the ABC screen, so now I have to switch screens to use punctuation characters.

Welcome to Android Central! Which phone do you have, and which keyboard? The stock keyboard probably won't give you much of an option. You could install a 3rd party keyboard. Google Keyboard allows you to change the theme to light or dark.
