RAL 2009 or similar statement colour, you only have one exclusivity chance, take it! Every time you walk in the room you will turn them on, no chance they will drift into obscurity. Forget the future resale value and live on the edge.
However fingerprints will be a problem every, visitor will involantarilly lovingly touch them. Just my experience.
Very interesting... I saw the McLaren Volcano Orange 5200SE's on a web site and I thought a pair of 8K's in that colour would look stunning. I'm just not sure I'm brave enough

I do think however that it the ultimate "statement piece" colour for 8k's!
