The red leather, for me, is a bit too bright with the Sport White (Ivory). Saddle Brown (tan) or Mulberry seem to be the two best choices.
Deciding is all part of the fun.
I am in agreement with you Peter. I really love my Ivory/Saddle colour combo, but your Ivory/Mulberry scheme is stunning also.
I think the Sand is also a classy colour for a trad, but I personally feel it needs a bit of a colour contrast here and there to freshen the look a bit....just thinking about how it might look after living with it for a few years.
