A chart uses very similar colour shades for different categories and no patterns. What will happen in a black-and-white printout?

Answer and explanation

Correct answer: Categories will be difficult to distinguish

The governing concept is accessible visual encoding: a chart should not depend on colour alone when it may be printed, viewed by someone with colour-vision difficulty or reproduced in grayscale. Similar shades become nearly indistinguishable without patterns, labels or strong contrast, so option B is correct. Printing does not automatically alter data values, remove the title or reverse the axes.
