Creates a Color structure from the four 8-bit ARGB components (alpha, red, green, and blue) values.

Overloads

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

Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. The code performs the following actions:

Creates three brushes, each a different color. Each Color structure that is used to create a brush is created from four component values (alpha, red, green, blue).

Paints three overlapping circles, each centered on one vertex of the triangle, using a different brush for each circle.

Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. The code performs the following actions:

Creates Color structures from the three color component values (red, green, blue). Three Color structures are created, one for each primary color.
Iterates through a range of alpha values, changing the alpha value of a color.
During each iteration, sets the color of a brush to the modified color and paints a rectangle to show the color.
Repeats steps 2 and 3 for each primary color.

The alpha value is never fully opaque and the rectangles overlap so you get color-combination effects.

Remarks

The byte-ordering of the 32-bit ARGB value is AARRGGBB. The most significant byte (MSB), represented by AA, is the alpha component value. The second, third, and fourth bytes, represented by RR, GG, and BB, respectively, are the color components red, green, and blue, respectively.
