Hi Marco,

We provide a ThemeColor only for action and visual components, where it makes sense to convey additional information with color:

• AppBar
• Badge
• Button, DropDownButton, SplitButton
• Card
• Dialog, Window
• Icons
• Loader
• Notification

In addition, the Grid already uses the Primary theme color for its sort arrows and the active state of the filter /column menu. The introduction of a ThemeColor will either make the Grid header too multi-colored, or inflate the CSS theme with new styles that readjust the color palette of the component for every ThemeColor.

Here is how to reuse the built-in theme colors for the Grid headers with custom CSS: https://blazorrepl.telerik.com/mzOrnOEq55GuaMzE00

You can also change the accent color of all components, or for a specific component, if this is what you are after. To override the theme colors for a specific component, use a custom component class instead of :root in the CSS code.

Regards,
Dimo
