Thank you for your feedback on the newly developed Metro theme.
It is intended to serve as a base and easily provide color variations to suit the needs of our customers.
The default accent color for the Metro theme is blue. You can go ahead and try changing the accent color and see your metro controls change accordingly:
MetroColors.PaletteInstance.AccentColor = Colors.Red;
For the background color, on the other hand, change the MainColor:
MetroColors.PaletteInstance.MainColor = Colors.LightCoral;
I hope this helps.
All the best,
the Telerik team
