If Statements - Populating cell data based on zip code list

I have a list of zip codes and I'd like to associate a color code to a particular zip code. I have the list of colors that belong to the zip codes and want a formula that will populate the color code to the zip codes as I'm constantly looking at new data and having to fill in the data.

This is what I have so far =IF(B3=I3:I20, "Blue", IF(B2=I21:I34, "Orange", IF(B3=I35:I56, "Purple", IF(B3=I57:I74, "Yellow")))) but it only worked for one cell and the rest are showing errors. B3 is the cell where the zip code in question is and column I is the column where I have all zip codes sorted by color.
