Centians currently have simple profiles that show their basic information along with their posts and replies.
Navigate to your profile by clicking the "Menu" icon in the top-left of your screen and selecting your username.
What are user colors?
Each Centian (or, rather, the first 16.7 million) can choose a unique identity color from the 16,777,216 different hex colors available. These colors will begin to appear in many places throughout the UI and will come to signify a myriad of user actions.
To change your User Color, click the colored circle in your profile, select a color, and click "Save".
