The colors above pertain to the European markets so those outside of the Old Continent might get a different palette.
There's a high chance Huawei will announce the P20 series at the Mobile World Congress in one month's time. We don't know a lot about the new phones but rumors suggest that the P20 and P20 Plus might have a triple camera on the back as well as some Face ID-type of authentication that will be faster than Apple's.
One of the soon-to-be P20's is likely to have a notch that will likely house this new tech.
