Alpha blending is the process of combining a translucent foreground color with a background color, thereby producing a new blended color.

Alpha blending is the process of combining a translucent foreground color with a background color, thereby producing a new blended color.

The degree of the foreground color's translucency may range from completely transparent to completely opaque. If the foreground color is completely transparent, the blended color will be the background color. Conversely, if it is completely opaque, the blended color will be the foreground color. Of course, the translucency can range between these extremes, in which case the blended color is computed as a weighted average of the foreground and background colors.
