TRIO THEMES
Every theme the library holds, on two Podium screens.
A theme defines your application’s color, type, spacing, shape, depth, motion and layout.
Compare every theme on two screens we use to run our business: the Inbox and the Pipeline map. The Inbox labels messages awaiting a decision so we can assess them before opening them. The Pipeline map shows five development steps: the request, design, code, testing and release.
The same Podium screens appear on the home page under "What runs today".
Each card below is a picture of Podium, the app we use to run our business, with sample data, taken at desktop width and scaled down for this page. The library holds 36 themes, grouped by family. Sunset Boulevard, Velvet Stage and Brutalist Concrete are the three on this site; the larger pictures further down keep Podium's own three: Warm Paper, Night Console and Engineering Calm.
Screenshots on this page use Podium sample data; they are not production records.
New Themes
October 5th, 2026, eleven new themes, found three ways: read from two award-winning sites; read from four other sites whose theme held up (names withheld); and five drawn by the factory.
What the Contrast Labels Mean
Each card reports how clearly the theme’s text stands out against its background. We measure every text and background pairing against the web’s accessibility guidelines (WCAG):
- Meets AA: all text stands out from its background by at least 4.5 to 1, the level accessibility rules usually ask for.
- Meets AAA: the strictest level. Text stands out by at least 7 to 1, the outline that shows where you are when you use a keyboard is at least 3 pixels thick, everything you tap is at least 44 pixels across, and decorative motion is off.
- Below AA: at least one pairing falls short; the label shows the worst one.
Today: No theme in the library falls below AA, and the library refuses any new theme that would.

How a Trio Is Chosen
Every app ships with a Trio: three complete themes users can switch while the app runs. We compare type, spacing, shapes, depth, motion, layout and icons to ensure the themes offer distinct choices. Each of the seven must vary within the Trio; we aim for three different treatments on at least five.
The three on this site, Sunset Boulevard, Velvet Stage and Brutalist Concrete, differ on all seven.
We suggest three themes from the library of 36 for you to consider. The selection reflects your industry, preferred mood, information density and accessibility requirements. You make the final choice through one of these approaches:
- pick all three yourself from the themes on this page;
- Choose a public website whose design suits your application, and we use its colors, type, spacing and shapes to draw a new theme. Six of the eleven newest themes started from a public website.
- Describe a direction, such as "Renaissance fair", "disco" or "cowboy", and we draw a new theme. The other five new themes began with descriptions of this kind.
Today: We help you choose three distinct themes and save them for your project. Our recommendations meet the distinctiveness requirements and include one theme that meets AAA. We measure contrast and review every new theme on real application screens before adding it to the library.
Tomorrow: We plan to let you select your Trio directly and apply it to every screen we build for your application.
Running: the three-theme switch at the top of this page uses the same engine as the switch every app we ship must have.
