For each bathroom choose a neutral color that U see in the tile Here is how to find the perfect wall paint "match" http://www.lindaholtinteriors.com/2011/07/testing-wall-color-101/

house is good in white. ensure you choose off white colour such as cotton woll and not brilliant white whike repainting. Gate in black. boundary wall in mud colour. overall it would look like a spanish villa. only thing missing is a big olive tree or a palm tree

Hi not clear about furniture color combination...we have to think about over all color combination... if you like grey color go with lighter shade like Gentle grey...here attaching some reference images take one combination.

Hi Chayya, For a contemporary style kitchen, you can go for a monochrome theme for the entire kitchen like a matt grey with brass seamless handles. It can be a good option with a white backsplash. You may also consider combining brown patterned finished shutters with lacquered white finish for a clean, contemporary look. Hope these suggestions help you
