The Colors Feature
The Colors feature is something that makes one color of your photo stands out and filters out the rest of the colors.
To make Colors both super easy-to-use and cool to the users without exposing its complexity to them, I used a solution that has the very same UI and UX as the AirBrush filterpack, something users are familiar with, instead of using the other 2 HSL-like iterations I had.
The feature is widely used, and participants from our user research found it cool and easy-to-use without understanding what it actually is. Most importantly, it's a paid feature, and it did bring in revenue and converted non-paying users to subscribers.
A prototype I used for usability tests as well as internal team communication
