You should pick up what I am using for my "rope lighting" in my home theater. 16.4 feet (5 meters) of color changing lights. Just need to hide the power supply and control unit. You can cut the strip every 3-4 LEDs (I don't remember) and then run some small wires to the next "piece" under the next cabinet. Comes with a remote. It is only something like $32 for the whole thing, and others have tested that you can add another full 16.4 feet to the end of one set using the same power supply, etc...
It is cheap, but a bit of work to get done. Then you could have it on white, or some other color that compliments your decor or mood. Fully dimmable too (via the remote)...
Again, it *could* be cool to do, but would take a bit of work to solder the wires and run everything.
