What color would a very hypo reflective, thin layer of the retina appear on an OCT scan?

Explanation:
On OCT images, brightness reflects how much light is backscattered from tissue. A very hypo-reflective area means it backscatters very little light, so it appears as dark on the grayscale image. Even if the layer is thin, the lack of backscatter makes it show up as black rather than white or gray. White would indicate high reflectivity, gray intermediate reflectivity, and red isn’t used in the standard grayscale OCT representation.
