What should a normal and healthy tongue look like? What is unhealthy?

A healthy tongue is like this: the color of the tongue itself should be reddish and moist, and the tongue coating should be thin, white and even. When spitting, the widest part of the tongue should not exceed the width of the corner of the mouth; Of course, you can't take a thin tongue as cute. Stick your tongue out of your mouth without feeling too dry or wet.
