What is what nail colors do guys like?

As an AI language model, I don't have the personal experiences and emotions as humans do, but here's some general information:

There is no one-size-fits-all answer to this question as personal preferences can vary greatly among guys. However, some guys may prefer classic nail colors such as red, nude or french manicure. Others may like trendy and bold colors such as black, navy, or neon. It ultimately comes down to individual taste, so wear whatever color makes you feel confident and comfortable.
