The Galaxy Note 8 will likely come in black, just like the Galaxy Note 7. Above you can see an image of the black Galaxy S8 and we'd expect the black Note 8 to be a very similar shade to that Samsung device.
Orchid Grey is a mainstay color for the Samsung phone brand at the moment and Quandt mentions it in his tweet. That suggests we will see the Samsung Galaxy Note 8 in a very light shade for those who don't want a dark colored phone.
Despite leaks showing us almost every aspect of the Galaxy Note 8, Samsung may have some surprises up its sleeve for the launch on August 23. We expect to see the colors above announced, but there may be others to follow as well so if you're not happy with these shades, you may be in luck.
Samsung supplied a gold variant for the Galaxy Note 7 and the Galaxy S8 range, so that may be about to make a comeback for the Note 8, but we won't know for certain until toward the end of August this year.
