Colors are not used to differentiate classes for multiple reasons. 20 classes like in the Pascal VOC case would not have great color differences and might not be color-blind friendly. Letting the user customize colors would also add a configuration burden and thus prevent us from reaching our goal of simple efficient annotations. Instead we strive for the best defaults possible, by relying more on contrasts than hues. Please share your use case here if it is a problem in your case.

From ACM MM18 review:

As the color of the line is fixed, it is difficult to do the annotation when the color of the image is similar to the color of the line as shown in the image.
