Color Structure

Represents an ARGB (alpha, red, green, blue) color.

Namespace: System.Drawing
Assembly: System.Drawing (in system.drawing.dll)

[SerializableAttribute] 
[TypeConverterAttribute(typeof(ColorConverter))] 
public struct Color
/** @attribute SerializableAttribute() */ 
/** @attribute TypeConverterAttribute(System.Drawing.ColorConverter) */ 
public final class Color extends ValueType
Not applicable.

Named colors are represented by using the properties of the Color structure. For more information about these colors, see Colors by Name in the MSDN Library. To determine the alpha, red, green, or blue component of a color, use the A, R, G, or B property, respectively.

You can create a custom color by using one of the FromArgb methods.

The following code example demonstrates the G, B, R, and A properties of a Color, and the op_Implicit member.

This example is designed to be used with a Windows Form. Paste the code into the form and call the ShowPropertiesOfSlateBlue method from the form's Paint event-handling method, passing e as PaintEventArgs.

private void ShowPropertiesOfSlateBlue(PaintEventArgs e)
{
    Color slateBlue = Color.FromName("SlateBlue");
    byte g = slateBlue.G;
    byte b = slateBlue.B;
    byte r = slateBlue.R;
    byte a = slateBlue.A;
    string text = String.Format("Slate Blue has these ARGB values: Alpha:{0}, " +
        "red:{1}, green: {2}, blue {3}", new object[]{a, r, g, b});
    e.Graphics.DrawString(text, 
        new Font(this.Font, FontStyle.Italic), 
        new SolidBrush(slateBlue), 
        new RectangleF(new PointF(0.0F, 0.0F), this.Size));
}

private void ShowPropertiesOfSlateBlue(PaintEventArgs e)
{
    Color slateBlue = Color.FromName("SlateBlue");
    ubyte g = slateBlue.get_G();
    ubyte b = slateBlue.get_B();
    ubyte r = slateBlue.get_R();
    ubyte a = slateBlue.get_A();
    String text = String.Format(
        "Slate Blue has these ARGB values: Alpha:{0}, "  
        + "red:{1}, green: {2}, blue {3}", 
        new Object[] { (UInt16)a, (UInt16)r, (UInt16)g, (UInt16)b });

    e.get_Graphics().DrawString(text, 
        new Font(this.get_Font(), FontStyle.Italic), 
        new SolidBrush(slateBlue), 
        new RectangleF(new PointF(0, 0), 
        Size.op_Implicit(this.get_Size())));
} //ShowPropertiesOfSlateBlue
