Boom, whacker color note heads

I’ve been attempting to create a customized note headset that color codes, the note by pitch matching the boomer colors. However, when I get to the open notes for whole notes and half notes, etc. it will not color the note head but only fills in the center. This will be confusing for elementary students.How do I correct this or do I need to use a different software and ask for my money back?

Does this work for you?
