How can I tell the difference between a ripe banana and a green one?

The best way to tell if a banana is ripe is by its color. A ripe banana should be yellow-green in color, with no brown spots or blemishes. If it has any dark spots, it's not yet ripe. You can also check for ripeness by gently squeezing the banana - if it yields slightly to your touch, it's probably ready to eat.
