Как изменить цвет скелета в Kinect SDK 1.8?

Предполагая, что вы используете код из Skeleton Sample, вы можете изменить значения в этих кистях:

    /// <summary>
    /// Brush used for drawing joints that are currently tracked
    /// </summary>
    private readonly Brush trackedJointBrush = new SolidColorBrush(Color.FromArgb(255, 68, 192, 68));

    /// <summary>
    /// Brush used for drawing joints that are currently inferred
    /// </summary>        
    private readonly Brush inferredJointBrush = Brushes.Yellow;

К любым значениям RGB или любым предопределенным цветам в Brushes, например.

    /// <summary>
    /// Brush used for drawing joints that are currently tracked (red)
    /// </summary>
    private readonly Brush trackedJointBrush = new SolidColorBrush(Color.FromArgb(255, 255, 0, 0));

    /// <summary>
    /// Brush used for drawing joints that are currently inferred
    /// </summary>        
    private readonly Brush inferredJointBrush = Brushes.Blue;
