Changing text colour in a cell based on value or colour of another cell.

Hi guys and girls, im wanting to be able to change the colour of text in a cell based on the value of another cell. So in my simple attached excel file. I would like cell C5 to have red text if cell B5 is greater than cell B3.
I assume its maybe some conditional formatting with an "if" formula but im not sure the correct way to write this.
Alternatively if Cell C5 could be changed to red text if cell B5 was red text that would work as well. Whichever way works would be ok. Thanks for any help that can be provided

Kind regards John
