Color blindness is an important thing to think about when we create charts and graphs. It affects how we choose colors for our data visuals.

Things to Keep in Mind:

1. Choosing Colors:

   • It's best to skip red-green color combinations. Many people who are color blind have trouble seeing these.
   • Use color palettes that are friendly for everyone. Good options include Color Universal Design (CUD) or Tableau’s color sets.

2. Making Colors Stand Out:

   • Use colors that are very different from each other. This helps people see the information more clearly. For example, pairing a dark color with a light color can work well.
   • Add patterns or textures along with colors to share information more clearly for those who struggle with color blindness.

Examples:

• If you use red and green in a bar chart, someone who is color blind might get confused. But using blue and orange makes it easier to understand.
• When showing data, it's helpful to label important points clearly so everyone can tell what they are, no matter how they see colors.

By being careful with our color choices, we can make sure our visualizations are clear and useful for all kinds of people.
