Consider the material. Is the weather likely to be hot? A rubberized raincoat may be uncomfortable. I can't read any details but sometimes they are made with holes like portholes under the arms for breathability.

If the white raincoat is plasticized or rubberized it will clean easily, otherwise if it is a cloth material it will get filthy so avoid white cloth even though it is nice looking.

Yellow is cheerful in rain. I like the beige (although it may be too boring for you) and the red. Consider the length and make sure there is a hood - I think all of them have it but I can't tell for sure.
