BTW, you can ask Joe to make them white or black - your choice. He will also do custom bolt spacing too.
Best to ask him for some spare 1/4x20 cap bolts too - I assure you, Bunnings DON'T stock them! (though one local hardware store DOES) He included 12 for me, gratis.
Just be careful with the paint for a while - mine were still quite fresh/soft, so let them harden a while before bolting anything strenuously to them

Not sure if he offers an anodised option, but you could ask.
I have Tak green paint if you want to go that route too - though all your gear is hidden under a metric tonne of cables, so you can't see hem anyways
