Samsung’s next-generation flagship phones are the talk of smartphone fans right now, and everyone is eager to finally get their hands on the new Galaxy S6 and Galaxy S6 edge. The phones mark the start of a new era at Samsung, where the company’s high-end phones will finally feature premium materials to match their gorgeous displays and cutting-edge internal components. Samsung revealed just about everything there is to know about the new phones during its Mobile World Congress press conference last week, but it looks like there are still a few secrets that have yet to be revealed.

When Samsung unveiled the new Galaxy S6 and Galaxy S6 edge, it said that each phone will be available in four different colors. Common among them are white, black and a sleek pale gold color, and then the S6 will also come in “Blue Topaz” while the S6 edge will be made available in “Green Emerald.”

According to an apparent slip up on Samsung’s website, however, there’s something the company isn’t telling us.

While each of the phones will sport four color options at launch, there is apparently at least one model with a fifth color on the way. Samsung loves tweaking its smartphones with new features after they’re released, so the move shouldn’t come as much of a surprise.

As noticed by Phone Arena and shown in the screen capture below, the Galaxy S6 shows a brown color option on Samsung’s UK website.

It is not currently clear when the new color option will be made available to the public, but the Galaxy S6 launches in its first four colors early next month.
