Just because a patio umbrella is missing a part doesn't mean that is has to be thrown away, which is good news, since a good-quality patio umbrella can be expensive. It can also sometimes be difficult to find a new umbrella that matches an existing patio set. Many companies offer replacement parts for patio umbrellas, including replacement umbrella canopies and replacement umbrella frames; these parts are typically inexpensive and fairly easy to change.
I would think it is possible to buy only an umbrella for your patio set. Most patio sets, sold by stores, can order replacement parts for you, regardless of the color that piece may be. Check with the store to see if the manufacturer has a replacement umbrella.
Depending on the size, many sites online sell replacement canopies. Startwith sites like www.marketunbrellasite.com or www.patio-umbrellas.com to see if they have your size in stock. Additionally you can try www.shadeusa.com or www.homedecorators.com
