W-ROYGB stands for which concept in OCT imaging?

• A. Acronym for color scale on OCT
• B. Retinal layers name
• C. Noise filter
• D. Pupil measurement

Answer: (A)

In OCT imaging, data such as depth or reflectivity is often shown with a color map so you can quickly see where values are high or low. W-ROYGB is a specific color ramp used for that purpose: White at the top represents the maximum value, then Red, Orange, Yellow, Green, and Blue represent progressively lower values. This makes features with strong signals or greater thickness pop out clearly against cooler colors. It’s not describing retinal layers, filtering noise, or measuring pupil size—it's about how the image data is color-coded to convey quantitative information visually.
