Avenue Logo HD Application

The background is darkened in proportion to how white the Alpha is. This means that the Alpha signal
itself never contributes to the image the viewer sees—it only controls how much of the background or
foreground is displayed. It will then look like this:

The RGB (color) portion of a logo. It has been

constructed over a black background.

The Alpha portion of the logo. Note that the

Alpha portion has two elements: (1) a white

section which matches to the text in the

RGB fill, and (2) a gray section which has no

corresponding element in the RGB portion.
