Your tile will co-ordinate beautifully with the timber if you can pick one of the darker colours out of the timber and select a tile in this family of colour. The trick to making a colour concept work is to either co-ordinate or contrast. If your timber is as busy with grain and colour as the image you've shown, then maybe co-coordinating is the best way to go. Never chose materials independently of each other - always take a tile sample home to see in the natural light, next to the timber. I hope it all works out the way you envisage it. Cheers, Michelle

I’d go with timber or cork. Cork is great in a kitchen. Easy on your feet and joints and things are much less likely to break if you drop them. Especially as you age, tiles cause fatigue if you are standing in the kitchen for too long. Cork is now available in lots of different colours and styles including charcoals and greys that might compliment your slate. It’s not all 80s orange. Of course timber can look great too. Just make sure it’s ok for kitchen use.

I agree that it can be upsetting at this stage but your timber will all darken naturally and the difference will become less obvious over time and once you have furniture and rugs in place it's likely to be one of those issues that only you and no one else will notice. And I defy anyone to not have something like this in their house which has been newly built/renovated. I know this isn't terribly helpful but I don't think ripping anything up to start again or going to great lengths to seek recompense from supplier/installer is going to help your blood pressure either (by all means raise concerns with them and ask for suggestions from them).

I have came across waterproof laminate floor with 15 years waterproof warrenty. Please see Quick Step Laminate Impresive Ultra floor boards. They look quite impresive. I am trying to decide between waterproof laminate and hybrid floor. Please see my post here https://www.houzz.com.au/discussions/6004056/laminate-vs-hybrid-waterproof-floor-board#n=0 Can you please give your input?
