In observance of the World AIDS Day Dec. 1, Apple has turned its logo "red" in some of its Apple stores in the U.S. and Europe. The bright white Apple logo was covered in red tint to show the company's support for AIDS awareness.

World AIDS Day is observed every first of December annually. It is a chance for people to remember their loved ones and friends they have lost or those that they know suffering from the disease.

The World AIDS Day Web site provides an opportunity for people to learn more about HIV. People are encouraged to wear a red ribbon on this special event. The red ribbon is an international symbol to support HIV awareness.

Apple customers can also show their financial support when buying red Apple products such as red iPods and cases for iOS devices. Apple Inc has dedicated some of its display tables in stores to Product (RED) versions of Apple's items for sale. When customers purchase one of these products, Apple will donate a portion of the sales to the Global Fund to Help Fight AIDS in Africa.

Apple CEO Tim Cook tweets the company's support:

Apple has been helping raise HIV or AIDS awareness for many years, including the Product (RED) items which the company has been selling since 2006. The program was designed Bobby Shriver and U2 Lead Singer Bono. The singer praised Steve Jobs for raising awareness and acknowledged Apple as the biggest contributor to the Global Fund to Fight AIDS. Bono said Apple's involvement has also led other companies to step up and do their part.

In November, Apple's Lead Designer Jony Ive and Industrial Engineer Marc Newson worked together to auction off various products to help raise money for the Global Fund. The products in the auction were a Product (RED) Mac Pro which was bought for $977,000 and gold Apple earpods that went for $461,000.

A 1996 Dom Perignon bottled was also auctioned for $93,750. The largest auction proceeds went to a custom-designed Leica Digital Rangefinder Camera at $1,805,000 and the (RED) Disk at $1,685,000.
