I have created a drop down menu using data validation. The list that I used as the source for that data validation has different coloured cells, but the coulors havent transfered over to the drop down menu. How do I do that?

I created a data validation list for different types of accommodation, and I want the next cell to automatically lost the price for that type of room. So I attempted an IF formula, but I need multiple options and I don't know how to do that!
