How to change the color of labels in a Simulink project?

I have created a new "Utility" classification label in my Simulink project, so I can distinguish between the design files and utility files. After I create this "Utility" label, it is automatically assigned a green color which is very close to the default green color used for files labelled as "Design" (see image below). Is there a way to change the color of the label so I can actually see the different labels in the Dependency Analysis view?
