Recap

• Pick the right palette type for your visualization
  • use sequential to encode numerical information with order
  • use diverging to encode numerical information with a critical midpoint
  • use qualitative to encode categorical information
• map the color with the highest contrast of a sequential palette to the most important value
• for categories use a maximum of 6-8 colors
• test for color blindness using a CVD simulator
• check the contrast of your data and text colors
• avoid rainbow palettes!
