Repeats steps 2 and 3 for each primary color. Iterates through a range of alpha values, changing the alpha value of a color.Дuring each iteration, sets the color of a brush to the modified color and paints a rectangle to show the color. Three Color structures are created, one for each primary color.

ExamplesД¬reates Color structures from the three color component values (red, green, blue). Red, green, or blue is less than 0 or greater than 255. To create a semitransparent color, set alpha to any value from 1 through 254. To create an opaque color, set alpha to 255.

Paints three overlapping circles, each centered on one vertex of the triangle, using a different brush for each circle. Uses an imaginary triangle to position three circles. Each Color structure that is used to create a brush is created from four component values (alpha, red, green, blue).

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. Alpha, red, green, or blue is less than 0 or greater than 255.
