Track lighting got a bit of a bad reputation in the 1990s but when used properly it is still functional and beautiful especially for the kitchen. Pot lights aimed straight down will add general illumination but not necessarily hit the counter. An angled ceiling light on a track can put task lighting exactly where you need it. Undercabinet lighting can also achieve a similar effect. Combining both will make task lighting in the kitchen look effortless.
If you enjoy art in your bathroom accent lighting will show it off best. Recessed directional lights provide focused illumination for each piece of art — or in this case for an alcove dedicated to a sculptural bouquet of flowers.
However a grid of pot lights is not all you need for a balanced light scheme. Notice that this space also includes a pendant sconces and art lamps (more on those later) as well as a full wall of windows. Including at least three layers of light from different categories and in different locations eliminates strong shadows and adds a sense of sparkle that allows all the other furnishings to look their best.
