I love dark shades but from my experience oil stains on a dark shaded cabinets in kitchen specifically are more prominent.

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.

Visual below is similar case like your preference of using wooden texture laminate with black counter top & lighter floor. Check out misty oak, pine, birch... in laminates!
