WPF Application ResourceDictionary problem

Hi all,
I am writing a WPF application which uses styles to visualize controls in the application. I use separate resource dictionaries. ControlTemplates.xaml, Animations.xaml and a folder named Colors including different resource dictionaries to change the control colors on the fly. I am using MergedDictionaries to load styles such that;

Then i get an exception when loading resources like;

"A first chance exception of type 'System.Windows.Markup.XamlParseException' occurred in PresentationFramework.dll

Additional information: Cannot find resource named '{BackgroundBrush}'. Resource names are case sensitive. Error at object 'System.Windows.Media.Animation.SplineColorKeyFram e' in markup file 'Styles;component/Styles/Animations.xaml' Line 81 Position 34."

When i add the BlueColors.xaml resource dictionary in the Animations.xaml file everything works well. I need to use those resource dictioaries in separate files because all resources except color resources are common throughout the application.

Any help would be greatly appreciated.

In dictionary ControlTemplates add this to the beginning:

<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/Styles;component/Styles/Colors/BlueColors.xaml"/>
</ResourceDictionary.MergedDictionaries>
