Conditional Formatting Excel 2013 based on content in other cell

Hello,

I have a spreadsheet with columns that have targets and results next to each other. If the target is reached (=) or exceeded (>) I want the result font to be green. Conversely if the result is not reached (<) I want the result font to be red.

I've been searching and while there are a lot of formulas that deal with changing cell colours or font colours based on a number of set thing, but not based on whether the other cell content is =/> or < than the cell content you want to change.

Can this be done?
