Let's say I have a table with rows ranking different fruits. I want to fill cells with "Apple" or "Pear" with green and cells with "Banana" or "Grape" with red. How do I use a formula in conditional formatting to accomplish this? I feel like I should be using the OR function, but I'm not sure.

Apple Orange Banana Pear Grape
Orange Banana Apple Pear Grape
Banana Orange Pear Apple Grape
