Modern Theme Creator Tool

In recent months, Microsoft Power Apps has taken a significant step in modernizing model-driven apps with the introduction of modern themes. This new experience improves accessibility, visual consistency, and allows for more flexible customization.

Modern Theme Creator — is a tool within xrmtoolbox that allows you to create and preview Power Apps themes without having to generate XML and upload configurations. From a visual interface, you'll be able to choose the colors for your theme and publish it.

Model-driven apps now have a modern style by default, aligned with Microsoft's Fluent design system. This includes changes to typography, backgrounds, shadows, borders, the use of floating elements, and a more modern grid.

In the previous version, we could only change the colors of the app header, i.e., the top bar, while the rest of the controls remained blue. Now we can change the entire main theme, including the BPF, font, lookup theme, etc. And, if we so desire, the header bar, providing greater flexibility in modern controls regarding the corporate theme.

Let's see step by step how it works.

Step 1: Create a new theme

Step 2: Update a theme

The theme can be applied at the general environment level or per application. To do this, you must add the app ID in the space provided.

To download the tool, you can do so from the xrmtoolbox Store itself and if you want to access the code repo, you can find the solution in the following link:
