Just when it seemed like there was nothing more to leak about these new flagships with Samsung's Galaxy S21 series launching tomorrow, a new rendering has appeared online that reveals a limited edition color for Samsung's Galaxy S21 Ultra.

Official-looking marketing materials shared on Twitter by WinFuture's Roland Quandt show the top-of-the-line version of the Galaxy S21 in several finishes, including a never-before-seen brown. Ultra variants of Samsung smartphones usually come in paler colors compared to the baseline model - that doesn't seem to have changed for the S21 lineup.

According to Quandt's renderings, the S21 Ultra will be available in black, dark gray, silver, and white. These should be simple color names, but Brown could be Samsung's special signature color this time around.

In addition to the S21 Ultra colors, Quandt shared images of the Samsung Galaxy S21 Plus colors. If his renderings are authentic, the middle model will be available in black, white, violet, red, pink, and light blue.

Violet is also included in another leaked rendering by Quandt. This shows the entry-level S21 model in black, violet, pink, and white. The violet and pink models appear to have rose gold hardware, while the white model appears to have silver hardware.

We hesitate to take Quandt's information at face value. The Samsung Galaxy S21 color leaks we have seen so far do not match these images as they are authentic. Some reports have indicated that "Phantom Violet" is a key color in the S21 lineup, which can be seen in renderings of the S21 and S21 Plus, but does not appear to be available on the S21 Ultra.

The Galaxy S21, Galaxy S21 Plus, and Galaxy S21 Ultra will all debut at Samsung's Unpacked live stream event tomorrow, January 15. That means we won't have to wait too long to see the S21 in its stock colors.
