⚠ Common exam trap
A common mix-up: candidates confuse 'impressive visuals' with effective communication, or assume that more data equals better insights, when in fact simplicity and consistency are the hallmarks of professional dashboard design.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use consistent color coding for similar metrics.
Consistent color coding for similar metrics reduces cognitive load and helps users quickly interpret data without re-learning visual cues. In dashboard design, this aligns with Gestalt principles of similarity and proximity, ensuring that revenue metrics, for example, always appear in the same color across charts. This practice is recommended by data visualization experts like Stephen Few and is a standard in tools like Tableau and Power BI.
