How do you measure color values precisely using the Eyedropper tool and Info panel?

• A. Use the Brush tool to sample a color.
• B. Use the Eyedropper tool to sample a color; the Info panel shows RGB/CMYK/Lab values.
• C. The Eyedropper tool cannot display color values.
• D. The Info panel shows values only for the current pixel, not sampled points.

Answer: (B)

You measure color values precisely by sampling a pixel with the Eyedropper and then reading the numbers in the Info panel. Set the Eyedropper to Point Sample (1x1) so you grab the exact color of a single pixel rather than an average across an area. Click the point you want, and the foreground color updates to that sampled color. The Info panel then shows the color values for that sampled color in multiple spaces (RGB, CMYK, Lab), giving you exact numeric data you can use in your workflow. This method is accurate because you’re obtaining the color directly from the image, not guessing or painting over it.
