CompTIA Data+ DA0-002 (V2) Practice Question

A diverging palette is intentionally designed for data that diverges around a central, meaningful midpoint such as zero. It employs two contrasting hues-one for positive values, one for negative-with a light, neutral color marking the midpoint. Viewers can immediately perceive both the direction (above or below zero) and the magnitude of the change.

A sequential single-hue palette only encodes magnitude in one direction and cannot distinguish positive from negative values. A qualitative palette assigns unrelated colors to categories, so the viewer cannot infer order or direction from the hues. A rainbow (spectral) palette cycles through many hues with uneven perceptual steps; it lacks a clear neutral midpoint and can mislead by implying patterns that are not actually present in the data.
