Color System

Uranium UI has a color system that allows you to use colors in a more flexible way. Uranium defines color names and a regular color palette. Each theme can customize and override it. So, application theme can be easily changed.

Uranium Core provides a base color palette that can be used in your application. Each theme can provide their own colors. You can also use your own colors.

Configuration

You should configure default Theme resources in your App.xaml. Default resources are included in UraniumUI.Resources namespace, it can be defined xmlns:u="clr-namespace:UraniumUI.Resources;assembly=UraniumUI" as xml namespace.

You can either use only ColorResource or you can use StyleResource to get all theme resources.

If you're not developing a theme, you should use both of StyleResource and ColorResource to get all theme resources. Resources are separated, because you may need specific resources while developing a theme.
