Bathrooms are generally smaller and lighter tiles make the room look bigger. There is also the old stigma that whiter is cleaner. However, it's all personal choice and you can easily choose a darker color.

We have two storey house here in shimla . Please suggest the kind of tiles we can have . It should not be marble as the weather here is already too cold. Also do tell the colour of the walls we can keep. I would prefer grey (medium to light ) , beige , white colours for the walls . Please do tell the type of tiles keeping the colours in mind

that's what I meant. The cabinets below and above the counter can be finished with a light toned wood grained laminate. if you feel that is too plain, another option would be to go with light wood grain below and plain off white above. Maybe add a couple of wood grained shutters above also to break the monotony

Teal is a very trendy colour, but having it on all four walls may be an overkill in the kitchen, especially with that dramatic chevron dado tile. I hope at least the 4th wall is white! The cabinets have to be white too
