The word maroon has two completely unrelated meanings:

1. A dark brownish-red color, like the deep red of autumn leaves or certain gemstones. Many schools choose maroon for their sports uniforms because it looks bold and serious. You might have a maroon backpack or see maroon curtains in a fancy theater. The color sits somewhere between brown and red, richer and darker than pink but warmer than purple.
2. To abandon someone in a remote place, usually on a deserted island. In old sailing stories, pirates sometimes marooned their enemies on empty islands as punishment, leaving them stranded without any way to escape. In Robinson Crusoe, the main character is marooned on an island after a shipwreck. Today, people use the word more playfully: you might feel marooned at home during a snowstorm, or marooned at school when your ride forgets to pick you up. The word suggests being stuck somewhere isolated with no easy way out.
