To keep the leather on my XJ6 in good shape I use products from the UK called Gliptone - you can buy them through eBay (of course!). They supply dyes if you need them to patch cracks - they supply a precise colour match for your individual vehicle - plus cleaning and nourishing products, and they are the business. My car has an "Oatmeal" coloured interior which is about as light as the LR colour, though a different tone. It's a 14 year old car which has perfect leather despite the Queensland and WA sun and heat its been subjected to.
Our D3 has a black interior, which was not my preference but second hand buyers have to buy on model and condition, unfortunately. At least we've got a light exterior colour. If I was buying new I'd just go with plain white with almond, and spend the money that would otherwise have gone to metallic paint on an e-diff and cornering lights ....
