What color would a very hypo-reflective layer, thin layer of the retina show up as on an OCT scan?

Explanation:
On an OCT scan, brightness reflects how much light is backscattered from tissue. High reflectivity appears bright (white), while very low reflectivity appears darkest (black). A very hypo-reflective, thin retinal layer produces little backscattered signal, so it shows up as the darkest area on the image, i.e., black. Red isn’t used to denote OCT brightness in standard grayscale displays, and gray would indicate intermediate reflectivity, not very low.
