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

Explanation:
On OCT, brightness corresponds to reflectivity: highly reflective structures appear brighter, while less reflective ones are darker. A very hyper-reflective layer reflects a lot of light, so its signal reaches the maximum and shows up as white on the image. The thickness doesn’t change the color—it’s the reflectivity that sets brightness. Gray would indicate moderate reflectivity, black would be little or no signal, and red isn’t used in OCT grayscale displays. So the bright, white appearance is the best description for a very hyper-reflective, thick retinal layer.
