DA0-002 Data Governance Practice Question
A report uses red and green colors to indicate performance; a stakeholder who is colorblind complains. What is the BEST remedy?
⚠ Common exam trap
A common mix-up: candidates assume the best remedy is to simply change colors to a more colorblind-friendly palette (like blue and orange), but CompTIA often tests the deeper principle that color alone is never sufficient for accessibility—redundant encoding via patterns or labels is required to meet WCAG standards.

Correct answer & explanation
✓
Add patterns or labels in addition to color
Adding patterns or labels alongside color ensures that the data encoding is accessible to colorblind viewers without removing the informational value of color for those who can see it. This approach follows WCAG (Web Content Accessibility Guidelines) 2.1 Success Criterion 1.4.1, which requires that color is not the sole means of conveying information. In data visualization tools like Tableau or Power BI, this is implemented by adding shape markers or text annotations to series, preserving the original color scheme for non-colorblind users while providing redundant encoding.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Remove color entirely
Why it's wrong here
Removing colour discards the performance encoding entirely, so no reader gains the red/green distinction and the report loses information. It is tempting because it eliminates the accessibility barrier outright, and it would be correct if colour carried no meaning, but here it encodes performance and needs a non-colour redundant cue.
- ✗
Change colors to blue and orange
Why it's wrong here
Blue and orange still rely on hue discrimination, which many colour vision deficiencies impair, so the accessibility barrier persists. This suits general aesthetic or branding changes. Adding patterns, labels or icons alongside colour conveys the performance indicator through a non-colour channel, satisfying accessibility requirements.
- ✓
Add patterns or labels in addition to color
Why this is correct
Red and green differ only along the hue axis, which deuteranopia and protanopia collapse into similar tones. Adding patterns or text labels encodes the same performance status through a second, non-colour channel, preserving the report's meaning for colourblind stakeholders without removing the original palette.
- ✗
Use a different chart type
Why it's wrong here
Colourblindness is remedied by encoding status with a redundant non-colour channel, such as icons or text labels, not by swapping chart type. Changing the chart type leaves the red/green encoding intact, so the stakeholder still cannot distinguish performance. A different chart type suits questions about trend or distribution shape.
