I was thinking about black badges then saw the colored overlays (stickers) sold in the US (on eBay too I think).

They do carbon fibre, matte, brushed metal and even camo effects!
I decided to use some black electrical tape to test it out and (am between all black propellers or black/white). Easy and reversible way to see if you like it...
All blue could be interesting too.
I'm not keen on the carbon fiber though.

This thread has got me thinking about going for fresh OEM style badges and get a few sets of the overlays, I fancy changing up the badges, can make it seasonal and all!
