Blender Retopology Overlay

Haven’t heard much about this feature, but I’m seriously believing it to be the best go-to blender feature. However, I have seen someone actually change the color of the overlay, hell, even change the color of specific faces within the same mesh with this overlay active. And I don’t understand, is there any way to do this? Color coding loops is really super helpful for beginner retopo workflows and the constant blue can become very confusing.
