There are restrictions on which colour combinations you can choose. My dealer had a separate document with these. The document had "permitted" and "recommended" and "unavailable" options for each of the combinations. Hope this doesn't disappoint anyone who was planning Chili Red with the Blue Ray cloth/leather and a Mellow Yellow colourline...
Also, IIRC, the red door panels that come with the red lounge leather are slightly terracotta-ish, rather than the bright rooster red of the colourline. I also seem to recall that the lounge red leather comes with those red door panels (the interior world, not the colourline). I must confess I didn't look too closely because I wasn't speccing full leather, so I'd check with a dealer.
