how do you change to color on the Samsung Galaxy S 5 phone

[AC Question]

Every thing was in color from the time I bought my phone until about three months ago and it suddenly only was in black and white. I have gone thru all apps and cannot find how to get it back to color.

Power saving mode may also be set to grey scale, i.e., black and white. Check to see if power saving mode is on and try turning it off to see if it returns to colour. You can also set power saving mode to remain in colour and not black and white.
