This is information that is stored for image files that have a color specified for the image background. RGB triplet or a hexadecimal code is the form in which the background color is displayed.
You are given three separate pairs of numbers that represent the different color values of the RGB spectrum. The red color corresponds to the first value, the second for the green color, and the last for the blue color.
A hexadecimal code can be generated for these three values that can also be used to specify colors either on the web or in a graphic program.
