Scope for cut evaluation

From AGS with the ASET (Angular Spectrum Evaluation Tool) system based on on the angular position of the source of light being returned to the eyecolor. Light coming from 0 to 45 degrees is colored green, from 45- 75 is colored red, and from 75-90 is colored blue.
In most lighting environments the brightest light is coming from overhead, either from ceiling mounted indoor lighting or the sun in the sky outdoors. Therefore red can be thought of as light directly from the source, generally the brightest light in the environment. Green is light coming from lower on the horizon and is typically reflecting off walls or other objects in the environment, and is generally less bright. When looking at a diamond at close range the light from the very highest angular range is blocked by the head of the observer. This obscuration effect is colored in blue, and as we will see, has important implications for diamond design. Light that enters a diamond and is not returned to the eye is known as Leakage and is represented by either black or white, depending on whether the diamond is backlit or has a black background.color saturation cut verifier
