How do you assign colors to a pie chart?

Click the chart you want to change. In the upper-right corner, next to the chart, click Chart Styles. Click Color and pick the color scheme you want, or click Style and pick the option you want.

What should you avoid when using a pie chart?

The pie chart's primary limitation is that people are much better at comparing lengths and heights, as you would see in a bar or line chart, than they are at comparing areas within a pie. Further, the long tail results, or the thinner pieces of a pie, tend to become unreadable.

How can I improve my accessibility color?

Color accessibility best practices:

Make sure that form labels have a color that's easy to read; apply this to errors and feedback as well. Text and interactive elements should have a contrast ratio of at least 4.5 to 1.
