I would suggest you take out the cabinet that is to the right of the stove and use it elsewhere in the house -- perhaps in the bathroom or dining room with a hutch above it. Then, I would suggest you have someone install a lazy susan cabinet in the corner between the sink counter and the stove, meaning you would move the stove down a bit and have a small cabinet/counter top to the right of the stove. I would suggest you have the cabinets refinished in white and then paint the walls a pastel you like. If you would prefer white walls, then add white-painted crown molding and paint the ceiling a light neutral blue, such as Sherwin Williams Niagara Falls Blue. Then, I would suggest you choose a favorite accent color and use this sparingly in accessories like towels, pot holders, small vases or floral arrangements, and a valence above the triple windows. For a genuine 1940s look, you might have white ceramic square tiles with a rectangular red border installed as a back splash behind and above the stove. If you are replacing counter tops, I would suggest a light color such as white with a beige or light grey vein or striation for some sort of pattern. You might be able to find the same color and design in floor tile OR opt for a wood floor as another poster suggested.

The blue is awesome (grey is too trendy)! The reason it stands out to you is perhaps because it's the only real colour there. Bring in the blue in a window treatment, a small appliance that sits on the counter, a pretty tray or area rug. Also, it is more appealing often if there are more than 2 colours - so right now you have a white and blue colour scheme - bring in red or orange or fushia - something from the other side of the spectrum (like you did with the yellow flowers but in a more permanent way)!

Love the blue carpet. It's such a nice colour and you rarely see blue carpet!

The number you need for adequate lighting is dependant on the light fitting, its brightness and the angle the light will cover. The physical size of the fittings will also affect the number that looks best. Two very small fittings may give adequate light but look lost, while three larger ones could seem crowded. You may even find some very small fittings that work well as a group of six. Take into account the width of the surface as well as the length so you can ensure it is all well lit. You may be able to change the brightness of the lamp in the fittings to give a good work light in the number of fittings that look best. Avoid creating strong bright/dark contrast areas on a work surface. More overlapping less-bright light is better than few brighter ones that leave dark patches between them. Also consider whether there are other elements in the space that the group of light fittings could relate to, whether window mullions, cupboard doors, seating etc. If something else is creating a strong rhythm, decide whether you want to echo, or offset that or have the lighting as a background element that doesn't have a strong relationship to it.
