Just do and choose what you think is right. I like blue color too, but I don't think it is proper for sunglasses frame, maybe a little strange, lol, I can't imagine it. But maybe it will be good and cool on you.
Personally, I think so. It is widely thought that in order to appear mature and cool, men should wear dark-colored clothing, as well as sunglasses. Therefore, men tend to choose sunglasses with black or gray frames. However, in my opinion, men can also wear some bright-colored sunglasses. For example, the ones with blue or white frames. Therefore, I think men can definitely wear blue frame sunglasses and it is really cool.
