Figure 1: Color Accessibility
Figure 2: Font Size & Readability
Figure 3: Labeling Balance
Choose the best practice to apply for each design issue:
Keep red/green (familiar traffic light metaphor)
Use colorblind-accessible palette (blue/orange/purple)
Convert to grayscale only
Color is sufficient (no additional encoding needed)
Add distinct shapes to each condition (circle, square, triangle)
Add fill patterns to data points
Keep minimal legend with color only
Add sample sizes and units to legend
Use direct labels near data instead of legend
