2. In the left-hand Navigation bar, click on the Appearance option. This opens the Appearance panel.
3. (Optional) Select the theme to customize from the dropdown at the top of the Appearance panel
4. (Optional) Select a theme swatch from the available list of Swatches.
5. In the Colors section, you will see a list of color pickers. Each picker represents a different color that is used in the theme.
6. To customize a color, simply click on the color picker and select a new color. Repeat this process for each color that you want to customize.

Note: Customizing the colors of the theme will affect the appearance of all components in your Radzen Blazor application. Be sure to carefully select colors that will provide a consistent and cohesive look and feel for your application.

Hint: You might notice that Lighter color shades have opacity applied to them. This is done intentionally to keep proper color contrast ratios between background and text color pairs.

Advanced theme customization includes the ability to edit typography, borders, shadows, modify the spacing and sizing of elements, and override default global styles for individual components.

To customize a theme in your Radzen Blazor application, follow these steps:

3. Find the customization section or Radzen Blazor component to modify

• Typography such as base font size and font family
• Application or component background colors
• Base Icon size
• Predefined sets of theme Borders, Shadows and Transitions
• All theme defined properties and interaction states of Radzen Blazor components
