Food colouring may have gone out of fashion, but it seems McDonald's didn't get the memo.
The global food franchise has launched an "Angry Birds" burger range in its restaurants in China, to coincide with the opening of the movie of the same name.
The burgers, featuring either red or green food colouring in the buns, look weirdly inedible, and have been met with mixed opinions from Maccas fans.
According to Mashable, the colourful sandwiches include the "Naughty Green Pork Burger" with a pork patty, fried egg, lettuce, jalapenos, and "mystery sauce", and the "Super Red Burger" which features a double chicken sandwich with Louisiana-style hot sauce, a fried egg, and cheese.
