Rear Brake Caliper Colour on LEs, Pluses Etc

Here's a quickie for LE and Plus owners.

Seen a pic of an LE which had red rear brake calipers. My thinking is this is a DIY job, and not a standard thing ?

My Plus has red rear brake calipers. I think all LE's & Plus's came with red calipers all round as standard.

LE and Plus had red calipers all round

My LE has red calipers all round...

Although I think that the red against the blue (in my case) looks a bit odd.
