Design Plastic Parts

What kind of paint to use on plastic Skullcandy headphones?
I’m not sure, I need to paint the plastic part of the headphones to a full black color instead of the “skull candy” designs.
What paint do i use? Watercolor? or what?
<3 thanks~!
acrylic paint, you can buy it at walmart, target, any place like that
