Or are you saying that if I did try to call the event, nothing would happen?

This exactly. You could call the event, but all it would do is register all the IBlockColors again. It has nothing to do with recoloring the block itself. It just registers a handler for blocks.

So wait, do I add that to my BlockState json?

It would need to be there, but it would also need to have some code. Here is the documentation.

Before I attempt block states, is there another approach I could do? As in, refresh the block so it does the event again?

 

EDIT: one other issue I just realized. I'll need to set the item colour, but I'm not sure how I'd go from ItemStack to TileEntity.

Not that I found, and I spent a few hours doing this myself.

The event only fires once. There is no reason to fire it again as I explained.

I recommend a custom Capability for it, but you could just store the value in its NBT via ItemStack#getTag
