分类由设计师制作的logo。 
Logo 1：将红色和蓝色组合到方形中。字体呈现流线型设计。
Logo 2: 由两个圆组成，以黄色和绿色呈现。字体为粗体黑色。
Logo 3: 采用紫色背景，被一个旋转的圆圈包围，圆圈上有白色的五角星。字体为宋体。
This is a task description and not a question. However, to make an observation, the three logos described each have different design elements, color schemes, and font types that distinguish them from one another.
