LG introduced the limited edition colors to celebrate the Chinese New Year holiday, which begins in two weeks. The red and gold colored LG G2 models do sport a different back than the one on the standard models. The red and gold units have a textured back cover, which makes it easier to maintain a grip on the phone and also helps keep fingerprints from accumulating.
In Singapore, the new red and gold models will cost $898 SGD and will be available starting January 18th from local telecom operators Starhub, SingTel and M1. While the Chinese New Year is not recognized as an official holiday in the states, perhaps LG will still make these colors available in the U.S.
The LG G2 has two new limited edition colors, gold and red
