To store the values you can use a struct like this:

C#

public struct HSVColor
{
	public double Hue;
	public double Saturation;
	public double Value;
}

Then this method will populate and return one of these objects with the correct values.

C#

public static HSVColor GetHSV (Color color)
{
	HSVColor toReturn = new HSVColor();

	int max = Math.Max(color.R, Math.Max(color.G, color.B));
	int min = Math.Min(color.R, Math.Min(color.G, color.B));

	toReturn.Hue = Math.Round(color.GetHue(), 2);
	toReturn.Saturation = ( ( max == 0 ) ? 0 : 1d - ( 1d * min / max ) ) * 100;
	toReturn.Saturation = Math.Round(toReturn.Saturation, 2);
	toReturn.Value = Math.Round(( ( max / 255d ) * 100 ), 2);

	return toReturn;
}

If you need all decimal places just remove the Math.Round method call.
