Examples

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

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;
   array<Object^>^temp0 = {a,r,g,b};
   String^ text = String::Format( "Slate Blue has these ARGB values: Alpha:{0}, "
   "red:{1}, green: {2}, blue {3}", temp0 );
   e->Graphics->DrawString( text, gcnew System::Drawing::Font( this->Font,FontStyle::Italic ), gcnew SolidBrush( slateBlue ), RectangleF(PointF(0.0F,0.0F),this->Size) );
}
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 Sub ShowPropertiesOfSlateBlue(ByVal e As PaintEventArgs)
    Dim slateBlue As Color = Color.FromName("SlateBlue")
    Dim g As Byte = slateBlue.G
    Dim b As Byte = slateBlue.B
    Dim r As Byte = slateBlue.R
    Dim a As Byte = slateBlue.A
    Dim text As String = _
    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(Me.Font, FontStyle.Italic), _
        New SolidBrush(slateBlue), _
        New RectangleF(New PointF(0.0F, 0.0F), _
        Size.op_Implicit(Me.Size)))
End Sub

Remarks

Named colors are represented by using the properties of the Color structure. For more information about these colors, see Colors by Name.

The color of each pixel is represented as a 32-bit number: 8 bits each for alpha, red, green, and blue (ARGB). Each of the four components is a number from 0 through 255, with 0 representing no intensity and 255 representing full intensity. The alpha component specifies the transparency of the color: 0 is fully transparent, and 255 is fully opaque. 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.

Methods

Equals(Color)
Equals(Object)

Tests whether the specified object is a Color structure and is equivalent to this Color structure.

FromArgb(Int32)

Creates a Color structure from a 32-bit ARGB value.

FromArgb(Int32, Color)

Creates a Color structure from the specified Color structure, but with the new specified alpha value. Although this method allows a 32-bit value to be passed for the alpha value, the value is limited to 8 bits.

FromArgb(Int32, Int32, Int32)

Creates a Color structure from the specified 8-bit color values (red, green, and blue). The alpha value is implicitly 255 (fully opaque). Although this method allows a 32-bit value to be passed for each color component, the value of each component is limited to 8 bits.

FromArgb(Int32, Int32, Int32, Int32)

Creates a Color structure from the four ARGB component (alpha, red, green, and blue) values. Although this method allows a 32-bit value to be passed for each component, the value of each component is limited to 8 bits.

FromKnownColor(KnownColor)

Creates a Color structure from the specified predefined color.

FromName(String)

Creates a Color structure from the specified name of a predefined color.

GetBrightness()

Gets the hue-saturation-lightness (HSL) lightness value for this Color structure.

GetHashCode()

Returns a hash code for this Color structure.

GetHue()

Gets the hue-saturation-lightness (HSL) hue value, in degrees, for this Color structure.

GetSaturation()

Gets the hue-saturation-lightness (HSL) saturation value for this Color structure.

ToArgb()

Gets the 32-bit ARGB value of this Color structure.

ToKnownColor()

Gets the KnownColor value of this Color structure.

ToString()

Converts this Color structure to a human-readable string.

Operators

Equality(Color, Color)

Tests whether two specified Color structures are equivalent.

Inequality(Color, Color)

Tests whether two specified Color structures are different.
