Gmail adds coloured labels

I have blurred the images, but I had access to almost every beta features of gmail, strangely its not my official email that gets these features, but the email I use for receiving newsletters and obviously a lot of spam an average 500 email a day get into my inbox . Though my official email has reached 10% of the storage, and recieves almost no spam still does not even have access to IMAP or many other useful beta features, quiet strange how gmail decides on which email address should be invited for a new feature. I guess the only option is to have an email which should receive more than 50 email a day everyday
