Grey is a neutral colour and it compliments all other colors. You better go with grey tile shades with some interesting geometric pattern. Like this one here.

If you will like to go little different than Indian / traditional one, mint green colour is in trend and goes well with brick colour walls. Looks good if you have white appliances, crockery and some other elements that are visible with it. (Sourced from google images) https://goo.gl/images/Wyu1kR

Hi, Rajendra, there are three way of doing, firstly what you have chosen is go minimalist with all white, here you will have to add colors by decorating wall or adding a symbolic decor or art mural/painting which will bring you a joy while working. but if you neglect the importance of art work, the kitchen will be boring to use after 6 months of use. as we enjoy spices in our food , so do our eyes enjoy a sense of catchy colors too. second will be adding a contrast in with back splash with a back painted tempered glass or corian, this woks wonders. third, with the color of your choice, which will be permanent in the cabinate, but gives you a fresh sense to the whole kitchen, little color here and there will attract your eye and you'll appreciate your own choice/selection again and again.

Manpreet, Congratulations on your new home! You can go with BWP ply with laminates. You are right in your choice of matt and glossy laminates for base and wall cabinets respectively. Without knowing your tastes, I am taking a chance to suggest you 14541 for base and 21187 MR+ from merino catalog. It looks good. Thanks, Nitin CORNERSTONE DESIGNS Bangalore.
