Colors, palette and identity

The main colors of the screens shown here: the reasoning behind each choice and the character they give the project.

Brand blue

Why this choice
It shapes the logo and sets it apart from light surfaces, providing a stable visual reference.
What it conveys
Discretion and a recognizable identity.

Light sage green

Why this choice
It distinguishes selected filters and avatars without filling the conversation list with strong accents.
What it conveys
Calm and a welcoming personal space.

Natural white

Why this choice
It gives names and messages room and keeps conversation at the center of the interface.
What it conveys
Simplicity, lightness and order.

Type and imagery

Text hierarchy

Names, message previews and dates have distinct roles in the list. The brand introduces the identity; interface text stays concise to support browsing.

Image choices

The presentation uses a real screenshot of the local preview, showing the conversation list rather than a generic photograph. The phone makes the context of use immediately clear.
