When bringing in objects with “Use device style,” you will notice the object is now linked to the style by default. That’s because you need to update the Toolbox style to use the device style! Updating the Toolbox style makes it easy to mix and match Dark, Light, Classic, and custom HMI Styles. I bet you changed the default style to WinCC Light and started pulling items onto your first HMI screen, but you’re surprised that they look like the WinCC Dark style. Usually, you want all HMIs to have the same style, so keep the “Default style of the project” checked, and instead modify the Portal Project’s default style. I think WinCC Dark is great, but I suggest trying some of the others so that you are familiar with all your options in the future.

You can change Runtime Settings to several default styles that Siemens includes for free.

When you create a Comfort Panel in TIA Portal, it has a default style selected in its Runtime Settings. Siemens has released all the documentation you need to get started. Specifically, it focuses on how styling can work with the Siemens Open Library. This blog shows some practical examples of using HMI Styling in projects. Recently, I have been working with the HMI Styling section of the Portal Library, and I have found it very helpful. Siemens TIA Portal Libraries have helped me develop PLC and HMI code faster and manage it better.
