WebColorConverter Class

Definition

Converts a predefined color name or an RGB color value to and from a Color object.

public ref class WebColorConverter : System::Drawing::ColorConverter
public class WebColorConverter : System.Drawing.ColorConverter
type WebColorConverter = class
    inherit ColorConverter
Public Class WebColorConverter
Inherits ColorConverter
Inheritance
WebColorConverter

Remarks

The WebColorConverter class is used to convert a System.Drawing.Color object to a predefined color name or an RGB color value. It is also used to convert a predefined color name or an RGB color value to a System.Drawing.Color object.

Caution

You should never access a type converter directly. Instead, call the appropriate converter by using System.ComponentModel.TypeDescriptor. For more information, see the examples in the System.ComponentModel.TypeConverter class overview.

The following list contains the sixteen predefined HTML color names you can use:

  • Black

  • Blue

  • Cyan

  • Gray

  • Green

  • Lime

  • Magenta

  • Maroon

  • Navy

  • Olive

  • Purple

  • Red

  • Silver

  • Teal

  • White

  • Yellow

You can also specify a custom color by using a hexadecimal number, preceded by the pound character (#), in the form #RRGGBB. RR, GG, and BB represent hexadecimal values from 0 to 255 that indicate the red, green, and blue components of a color, respectively. For example, the value #0000FF represents the color blue. It specifies the minimum value (00) for the red and green components, while specifying the maximum value (FF) for the blue component.

Constructors

WebColorConverter()

Initializes a new instance of the WebColorConverter class.
