Why the color on the lcd screen of my Samsung galaxy tab 4 10.1 is off?

The color on my screen is off. All I was doing was a game on tablet and the color went off.

Welcome to Android Central! Do you mean it's in black and white now? Make sure you don't have Ultra Power Saving mode turned on. Or go to Settings>Accessibility or Settings>Display​ and look for a Grey Scale option.
