I have just done a small makeover on the mighty Sarawana, to bring her up a bit.I have the usual combination of Teak & Teak with Teak trimmings.
What I did , & I am very pleased with the effect was to replace all the lights with Warm LED's and also use Strip LED's under the counter top lips, these strip LED's are as cheap as chips easy to install and pick up the Teak beautifully when on.
The trick is to install then so you cannot see the directly when the power is on, what you get is that diffused indirect light, looks great.
Mind that is only good for night time, so if you want to lighten it in day light, maybe some soft cushion colour as Wifey B said. At the risk of incurring RT Firefly's wrath I have to agree with Don, I have seen some very good paint jobs on Teak. Especially where they use the light paint to pick up the Teak, that is not painting the whole cabinet say but the inner panel leaving the Original teak to frame the paint.
Cripes I am starting to sound like an interior decorator!
