The way that rooms are lit or highlighted by types of fixtures, shades and bulbs can have a huge effect on perception. There are studies which suggest that lighting can effect a person's mood.
When it comes to lighting the kitchen, there are several types needed. On the practical side, there is the work of processing and cooking food. Lighting should be planned to illuminate areas of food preparation. Canned ceiling fixtures spaced to brighten counter tops are always a good step.
low voltage under cabinet lights placed underneath the wall cabinets also assist in practical aspects, and combine well with the effects of canned fixtures. Track lighting or a sconce wall mounted fixture to highlight a small eating area if the kitchen is large enough for a small table or a dry bar with a couple of stools.
I remodeled a kitchen for lighting effects. where the entire ceiling was removed. I installed seven can lights over an L-shaped counter space. The customer also had me install six under cabinet lamps. Then, he had an island with a small sink and chopping block top over which I installed a set of three specialty lights made of brushed stainless steel. The lamps were sleek, funnel shaped with thin tubes mounted to a ceiling plate. Tree, at different heights. Together, all of these fixtures produced a nice spread and we decided to use the 60 watt bulbs, some of them were connected by a dimmer switch. The combined illumination worked well and highlighted the right places.
