DA0-002 Data Governance Practice Question
A company wants to ensure that data visualizations are accessible to colorblind users. Which of the following is a best practice?
⚠ Common exam trap
Watch out — candidates often think avoiding color entirely (Option A) is the safest approach, but CompTIA often tests the nuance that accessibility is about inclusive design—combining color with other cues—not eliminating color altogether.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Combine color with patterns or labels.
Combining color with patterns or labels ensures that information is conveyed through multiple visual channels, making it accessible to colorblind users who may not distinguish certain hues. This practice aligns with WCAG (Web Content Accessibility Guidelines) 2.1, which recommend using more than one sensory characteristic (e.g., shape, text, or pattern) to communicate data, rather than relying solely on color.
