Announcing MRTK Theming (Beta) for Canvas UI

We’re excited to introduce MRTK Theming for canvas-based elements, available in a beta package today! This new capability enables developers to easily define, apply, and iterate on visual styles across their UI—bringing greater consistency, customization, and scalability to XR and spatial applications.
With MRTK Theming, you can:

• 🎨 Centralize and manage UI styles across canvas elements
• 🔁 Quickly switch and experiment with different visual themes across platforms providing a theme or create custom themes!
• ⚡ Match the system UI of the platform your application is running on

This initial release is focused on empowering developers to experiment and provide feedback, helping us shape a robust theming system for MRTK going forward.

💡 What’s next?
We’re also working on a Material 3-based theme inspired by Google’s Android design language, arriving soon. This upcoming theme will showcase how MRTK Theming can bring modern, expressive design systems into immersive experiences.

👉 Get started with the beta package today and let us know what you think!
