Yellow is a good color for kitchens, because it's cheery and bright. It's almost like bringing sunshine into the house, and puts the cook in a good mood. Light green is also a good color, because it reflects the green color of many of the foods that will be prepared in the kitchen.
My choice of colours would be - a dark green marble for the table of the kitchen, a shade of mauve tiles to line the walls 2 feet above the table area, and the walls painted in a royal blue would finish off the look.
