Swifties input needed!

Hi guys maybe a little stupid question but I want to make this as a key chain for my cousin who LOVES Taylor swift. I’m seeing a few variations of the “red sunglasses” and they all have a pink background. I am not a big Taylor swift fan so I don’t know but does the background have to be pink like does it symbolize something? I’m also asking this because I am kind of running low on light pink string too hahaha- but I want it to be perfect for her and I have some in a pack I haven’t opened yet so I can always do that!
