The iPhone 6 Plus comes in three colors but the iPhone 6s Plus could come in four. The device is rumored to have the usual gray, silver and gold options but it's also rumored to be coming in pink. Rose Gold iPhone 6s rumors have been flying around as well.
The Galaxy Note 5 is rumored to be coming in four colors as well including white, black, silver, and white. While Apple is known for offering all of its colors at release, Samsung is known for offering only a few colors at release. Perhaps that will change this year with the pressure on Samsung to deliver.
