switching my iphone 13 color

so this might be something i should discuss with at&t but maybe you guys have went through this too? so i got my new iphone 13 like 2 and a half months ago? but when i got the phone the guy there didn’t even ask me the color i wanted, he just brought out a blue one. i didn’t want the blue one but i didn’t speak up. so i was wondering if even though it’s been over 14 days there would be some sort of exception, since i was in that situation. someone help please! i do not like this color at all!
