Color Marker is a small Outliner management script for Autodesk Maya that will allow you to add some colors in Outliner and Viewport(object(mesh) wireframes, locators, curves, deformers, joints, emitters...) making it way easier to see and arrange stuff if you are dealing with the heavy scene.
A lot of people complained about the new icons after Maya 2016 was first released, especially guys who are doing rigging/animation type of work. This script should hopefully make things a bit easier not only for rigging/animation type of work but also managing objects while modeling.
