How can I convert the values of three sliders into a Color?

Question

I\'m trying to create a custom user control that will allow a user to define a color in WPF. I\'ve done this before in WinForms but in WPF it seems to be not as straight for

Okay - I want to thank everyone for their help; I was finally able to come up with a solution - in the event anyone is interested or stumbles upon this, it's also a good lesson in MVVM (maybe; I don't know...).

Anyway :

This is the MVVM I implemented :

public class ColorViewModel : INotifyPropertyChanged {

    public event PropertyChangedEventHandler PropertyChanged;

    private Color _Color = Colors.Black;

    public double A {
        get { return this.Color.ScA; }
        set {
            this._Color.ScA = ( float )value;
            if ( this.PropertyChanged != null ) {
                this.PropertyChanged( this, new PropertyChangedEventArgs( "A" ) );
                this.PropertyChanged( this, new PropertyChangedEventArgs( "Color" ) );
            }
        }
    }
    public double R {
        get { return this.Color.ScR; }
        set {
            this._Color.ScR = ( float )value;
            if ( this.PropertyChanged != null ) {
                this.PropertyChanged( this, new PropertyChangedEventArgs( "R" ) );
                this.PropertyChanged( this, new PropertyChangedEventArgs( "Red" ) );
                this.PropertyChanged( this, new PropertyChangedEventArgs( "Color" ) );
            }
        }
    }
    public double G {
        get { return this.Color.ScG; }
        set {
            this._Color.ScG = ( float )value;
            if ( this.PropertyChanged != null ) {
                this.PropertyChanged( this, new PropertyChangedEventArgs( "G" ) );
                this.PropertyChanged( this, new PropertyChangedEventArgs( "Green" ) );
                this.PropertyChanged( this, new PropertyChangedEventArgs( "Color" ) );
            }
        }
    }
    public double B {
        get { return this._Color.ScB; }
        set {
            this._Color.ScB = ( float )value;
            if ( this.PropertyChanged != null ) {
                this.PropertyChanged( this, new PropertyChangedEventArgs( "B" ) );
                this.PropertyChanged( this, new PropertyChangedEventArgs( "Blue" ) );
                this.PropertyChanged( this, new PropertyChangedEventArgs( "Color" ) );
            }
        }
    }

    public Color Color {
        get { return this._Color; }
        set {
            this._Color = value;
            if ( this.PropertyChanged != null )
                this.AllChanged( );
        }
    }
    public Color Red { get { return Color.FromScRgb( 1.0F, ( float )this.R, 0.0F, 0.0F ); } }
    public Color Green { get { return Color.FromScRgb( 1.0F, 0.0F, ( float )this.G, 0.0F ); } }
    public Color Blue { get { return Color.FromScRgb( 1.0F, 0.0F, 0.0F, ( float )this.B ); } }

    private void AllChanged( ) {
        this.PropertyChanged( this, new PropertyChangedEventArgs( "A" ) );
        this.PropertyChanged( this, new PropertyChangedEventArgs( "R" ) );
        this.PropertyChanged( this, new PropertyChangedEventArgs( "G" ) );
        this.PropertyChanged( this, new PropertyChangedEventArgs( "B" ) );
        this.PropertyChanged( this, new PropertyChangedEventArgs( "Red" ) );
        this.PropertyChanged( this, new PropertyChangedEventArgs( "Green" ) );
        this.PropertyChanged( this, new PropertyChangedEventArgs( "Blue" ) );
        this.PropertyChanged( this, new PropertyChangedEventArgs( "Color" ) );
    }
}

This is the control class :

public partial class ColorDefiner : UserControl {

    public static readonly DependencyProperty
        _Color = DependencyProperty.Register( "Color", typeof( Color ), typeof( ColorDefiner ) );

    public Color Color {
        get { return ( Color )this.GetValue( ColorDefiner._Color ); }
        set { this.SetValue( ColorDefiner._Color, value ); }
    }

    private ColorViewModel CVM { get { return this.DataContext as ColorViewModel; } }

    public ColorDefiner( ) {
        InitializeComponent( );
        Binding B = new Binding( "Color" ) { Source = this.DataContext };
        this.SetBinding( ColorDefiner._Color, B );
    }
}

This is the XAML for the User Control (yes, I did it with a UserControl; this required a data context, and I really don't want to fuss with that yet in a Custom Control - this is really only going to be my own personal control for my own use anyway) :

I bound the Brush Color of the Labels to their respective colors in the View Model (A got the entire thing). I Two-Way Bound the value of each slider to it's respective value within the view model, and in the code I bound the Dependency Property to the view model Color property. I tested this, and it worked.

Once again, thank you all for your help.
