Which color represents high reflectivity on OCT images?

Explanation:
In OCT, brightness represents how strongly a structure backscatters light. High reflectivity means a strong backscattered signal, which the image encodes as the brightest pixels. Therefore, the areas with the strongest echoes appear white. Lower reflectivity shows up as gray or black, with the darkest regions having little backscattered light. Some devices color-code reflectivity, but the common representation uses white for high reflectivity, gray for mid, and black for low.
