I want some color options for "☆" stars on the mobile app

I would like to change the color of "☆". It's very dissapointing that the stars that were previously blue are now black... I wish I could choose the color of the stars.

If I can use the stars having a different color, it will be easier to categorize files and folders, especially photos. Depend on people who are in photos, I want mark favorite photos by defferent colours. For example, ｢red→my partner, blue→families, yellow→friends, green→colleagues｣, etc. Colourful stars will make starring more useful and pleasant, so I will use Dropbox app more frequently and recommend this app to many people.
