I went to my local Lowes store and ask if they had black paint for a 10 gallon Sterilite container. They told me they couldn't guarantee that any paint, even the ones that are for plastic would stick. They said it was due to the kind of plastic Sterilite uses and that most likely the paint would come off the first time the container got wet. I settled for using two rolls of Duct tape, this one for the black layer

and this for the white layer.
