Question

You are finalizing an executive dashboard that uses red and green filled bars to distinguish 'below target' from 'above target' KPIs. During review, a stakeholder notes that several executives have red-green color vision deficiency and cannot reliably tell the categories apart. Which change BEST improves accessibility while preserving the dashboard's meaning?

Accepted Answer

Add a text label or distinct icon/pattern to each bar and use a colorblind-safe palette in addition to color

Answer

Increase the saturation of the red and green so the colors appear more vivid on screen

Answer

Replace the bar chart with a pie chart so the categories are shown as proportional slices

Answer

Add a footnote explaining which color means below target and which means above target
