Aspects434 Hummzinger Humm Blossom Hummingbird Feeder

Would it be too confusing for the hunmers if I alternate the colors everyday while washing??

what is this feeder made of?

I was always told to make sure to buy a feeder that has alot of red on it since I use sugar water and not the red nectar stuff...will they still come to this purple one??

Hi! Can small bees fit through the ports? Thank You!
