Hint:

Now take some matt black paint from halfords and spray your hubs black too.... finishes the look.

Easiliy done, no need to remove the alloys, just aim in the gap and any residue will either be on the rear of the already black alloy...and on the disk, which will rub off on your 1st outing

Edited to add..looking closer you may have already done it?
