Use Windows Phone 8 theme colors in C#
Marco Franssen
5 min read•954 words
When developing Windows Phone apps, I love using the theme's accent colors. Windows Phone 8 adds some new ones, so I started looking for their color codes. Luckily, I found them on MSDN.
You may be wondering how to use these colors in your own Windows Phone apps. The Color type doesn't have a color called Emerald, so I created a small helper class. First, I added a static method that converts a hexadecimal color string into a Color value.
public static Color FromHexa(string hexaColor)
{
return Color.FromArgb(
Convert.ToByte(hexaColor.Substring(1, 2), 16),
Convert.ToByte(hexaColor.Substring(3, 2), 16),
Convert.ToByte(hexaColor.Substring(5, 2), 16),
Convert.ToByte(hexaColor.Substring(7, 2), 16)
);
}Then I added properties to cache the colors on first use. The Color properties look like this.
private static Color _lime;
public static Color Lime
{
get
{
if (_lime == null)
_lime = FromHexa("#FFA4CC00");
return _lime;
}
}Here's the complete class I came up with.

}If you're using this in an MVVM solution, you'll probably want a SolidColorBrush to bind your control to. Here's how you can use my class to create a bindable property in your ViewModel.
public class MyViewModel : INotifyPropertyChanged
{
private SolidColorBrush _myTextColor = new SolidColorBrush(PhoneThemeColors.Crimson);
public SolidColorBrush MyTextColor
{
get { return _myTextColor; }
set
{
if (_myTextColor != value)
{
_myTextColor = value;
OnPropertyChanged("MyTextColor");
}
}
}
#region INotifyPropertyChanged Members
public event PropertyChangedEventHandler PropertyChanged;
private void OnPropertyChanged(string propertyName)
{
var handler = PropertyChanged;
if (handler == null) return;
handler(this, new PropertyChangedEventArgs(propertyName));
}
#endregion
}I hope you found this article useful. Fork my gist on GitHub or paste the class into your own project, and share it with your friends.
