Diamond

The Diamond scope shows the interaction of RGB and helps identify RGB gamut errors in
digital video signals. The blacks are in the middle of the display where the two diamonds
join. The whites are at the top of the upper diamond and bottom of the lower. Blue and red
is displayed on the right and green on the left. If the image is balanced and is showing a
grayscale, most of the trace is centered and forms a vertical line.
