The Video Vector Scope provides a vectorscope display. This scope can be used to to evaluate the hue and saturation in the image. The presence of colors are mapped as a circle containing Red, Magenta, Blue, Cyan, Green and Yellow demarcations. The more samples that exist for a given value, the brighter the sample will appear in the display.
When the mouse is passed over the scope, a bubble appears to display the U & V values for the sample under the mouse.
The scope also includes a skin tone line, located at about the 11 o’clock point between the red and yellow demarcation points. It is common for colorists to center the skin tones around this line.
