I hate to break it to you but there is no such thing as beauty because everyone has something in their minds they created themselves and things need to fall in categories so they categorize their thing beauty, which is the class of things humans fail to describe. In reality, there are a few billions of such things and they are all different but called beauty.
Every once in a while by means of mind control or whatever some people manage to make a big group of mankind agree on what beauty is but that usually doesn't last very long as new beautifulness arises, falls out of fashion, then gets recycled every now and then.
I don’t know from where you got the idea of beauty being disfavoured. My impression has been the opposite, otherwise, we wouldn’t have the showbiz nor the industries that manufacture luxury items worth more than some human beings, nor design fails to make us laugh (what a life is without laughter).
Anyway, the key point is, there is no authority or some sort of function-cop who convicts you of creating beauty, just that sometimes your creations will not be appreciated by a lot of people, or even anyone, and if you are cool with that then make beauty your life pursuit.
