Overview
The platform provides a comprehensive theming system to ensure your applications are visually consistent, accessible, and aesthetically pleasing—across both the configuration environment (Designer) and deployed Runtime displays.
Themes are designed to adapt to different lighting conditions, user preferences, and branding needs. Whether you’re working in a bright control room, on a factory-floor tablet, or a dark monitoring station, the platform includes a curated set of themes to match.
All built-in themes apply automatically across the Designer and Runtime environments, with no extra configuration required. Custom Light and Dark themes can also be created using built-in theme tools, offering flexibility for OEMs and branded-label solutions.

Applying Theme Colors
You can apply themes in two primary ways:
• In the Designer:
Select the theme from the Welcome Page or via the User Preferences panel. Use the Properties Sidebar to configure brushes that dynamically adapt to the selected theme.
• In Runtime:
Apply a theme dynamically using the property Client.Theme.
@Client.Theme = "ThemeName";
Select Colors in the Designer
When drawing displays, the Properties Sidebar, has the colors editors, to select colors for Border, Fill, and Text Elements.
The THEME and HPG presents the colors that automatically changed, when a global theme is selected for the solution.
The THEME tab has the generic colors (the list is filtered automatically accordingly as you edit a background, border or text color), the HPG section has colors that following the specification for High Performance HMI Graphics.
When drawing the displays, the Properties SideBar has a section Appearance, with the Theme ComboBox.
That option will change the preview of the display, when running on the Designer tool.
When running the solution, change dynamically the Theme using the property @Client.Theme.
Working with Themes
Selecting a Startup Theme
You can select a pre-created Theme to startup your solution.
To do so, go to Displays → List, and click Windows button at Client Settings. It will open a popup window where the Initial Theme field is on the bottom.
If the field is left blank, the solution starts up without any theme using the objects properties used at the moment the displays were created.
Changing a Theme in Runtime
Theme selection in runtime can be done by using the syntax below in Script codes, Expression fields, or objects configuration.
To set the solution to the default configuration, without a custom theme, you need to set the Client.Theme to an empty string (Client.Theme= ””) or create an empty theme table and assign it to the theme property.
@Client.Theme = "Blue"; @Client.Theme = "Dark"; @Client.Theme = "Yellow"; @Client.Theme = "";
Theme Color Roles
The platform provides a structured color definition system. These colors are applied automatically by the system when creating UI controls, and can also be used directly in custom graphics, using the previously showed color selection dialogs.
The page Displays → Themes in the Solution Explorer has the full table will allow pre-defined theme colors. Those colors are organized in the following main groups:
- Theme Colors
- High Performance HMI Graphics
- Custom Colors
The General Theme Colors is organized in the following groups:
- General Theme Colors
- Main Backgrounds
- GroupBox Elements
- Diagram Elements
- Text Elements
