How to Highlight a word in color in paragraph?

I have a textarea with a long paragraph and i want to look for the word that appear in the paragraph. This word might appear multiple time and i want to color the word that is found in the paragraph red.

i am current using INSTR to look for the word but i am sure there is a easier way to do this perhaps using REGEX.

Maybe have a look at this:

thanks… i will take a look at this…
