Pie chart color refreshing

Quick answer：

Refreshing colors for pie charts are typically chosen to enhance readability and aesthetic appeal. These colors are often light, pastel, or neutral tones that do not clash or overpower each other. They can also include a few vibrant or contrasting colors to highlight specific slices or data points. The use of color gradients or patterns can also add depth and interest to the chart. When selecting pie chart colors, it's important to ensure that the colors are distinguishable from each other and that the chart is accessible to viewers with color vision deficiencies.
