After a long summer in the pool and the bright sun, your favorite rainbow-colored beach swimsuit will probably end up pale and faded. Pale means "having little color."
When something's light colored, you can describe it as pale, like a pale light shining in the kitchen at night, or a person's pale face when they're suffering from the flu. Pale is also a verb that means "to become pale," so you could say that you saw your friend's face pale at the news that her favorite bakery had gone out of business. Don't make the mistake of confusing pale with its homophone, pail, which means "bucket."
