Pie chart three-color color scheme

Quick answer：

A three-color color scheme for pie charts is a way to visually represent data with three distinct colors. This is often used to categorize data into three groups or to highlight different aspects of the data. The choice of colors should be based on contrast and readability, with consideration for color blindness. Common approaches include using a single color for the background, a contrasting color for the data, and a secondary color for emphasis or labels.
