Hi, did you mean to attach a photo?

Bluestone is beautiful and a dark colour is good for entry. Does the entry get a lot of natural light? If not you may be right to use a lighter colour. Can't settle your argument sorry.

Aside from how you want your kitchen to function, you need to consider what depths and hues can do for a space. Basically if you have high ceilings, darker cabinetry for your overheads can really draw the eye upward and highlight the feature but if your ceilings are standard it can feel heavy and encroach the negative space. Lighter overheads will reflect the light so the negative space will feel larger. Dark colours are also used to create depth in a room, to draw it back further visually. In my opinion darker lowers would work if you like the two tone look, it will break up the light flooring. Keep in mind you don't have to use colours that are contrasting, try pulling samples together that are a few shades deeper in harmonious hues, much like your picture provided. When it comes to the splash back you can opt for a texture in similar colour family to create interest without adding too many colours. Perhaps a penny round, hexagon, hand made subway or the same stone you choose for the benches. Don't stress about paint colours right now as there are thousands that you can choose to complement your kitchen. Hope this helps!

I can really recommend the Danish brand "Rug Solid, which have rugs made totally out of recycled materials. This is a photo from our living room, where we have a recycled cotton rug from "Rug Solid". http://rugsolid.dk/en/
