Is it possible to manipulate Array data

I am making a simple card game, and I have a bunch of text cards stored inside String array. There is this particular word inside each card that I would like to be highlited with a certain color (blue example). Is it possible to take a part of array item’s text and manuplate it?

Example: "Hello there, my name is ". Now think that this sentence is inside a string array. What I want is to turn the word “” blue text and let the rest be (default) white. Is this possible and if it is, how do I go about it?

Ps: I am working from a widget. This is for a game menu.
