Why are toilet bowls mostly white?

I always wondered, why are toilet bowls almost always white? I asked for an answer and got it.

There are actually two main reasons, and if you are interested in what they are, then here they are.

Toilet bowls are made of porcelain. This is a very solid material that is easy to clean and does not stain. That is why white cups are easy to clean and maintain. Since white is the cheapest color, then it is not surprising that all porcelain is painted white. In this way, toilet bowls become more affordable and cheaper.

Another reason why cups are white is psychological. White is associated with things that are the same and sterile, so when you see white in the bathroom, you have the feeling that you are entering a clean bathroom.
