It's very cool if you change the colors on certain wall but after a while you mainly want warm white. And warm white is not that good on a RGB strip (my opinion).
So I used a very good warm white LED strip instead.
I installed the LEDS (total 25 meter) on:
- behind all my curtains (12m)
- In the bathroom under my bathtub (2m)
- under the (hand)rail of the staircase (5m)
- in front of my house (6m)
I control the LEDS with two Chromoflex RS232 controllers
So the LEDS are completely dimmable and can be controlled per curtain, staircase etc.
Nice thing about thew Chromoflex controller that the controller is initially for RGB, so if you use only white LED strips you can control 3 LED strips independent.
So if my curtains close the LED lights go on automatic, If I'm not at home at night only the LED light go on, saving energy and from the outside give a good at home impression

The power usage in DIM (mood) mode is just around the 2.5 watt. If you need some bright light then you can get a huge bundle of light by setting the controller to max.
I can control everything with my domotica system and of course with Pronto 9600.
On the images below the light looks somewhat bright, but in real it's a very cozy (mood) light.
The LEDS on the staircase have a very good function, I keep them on till late making it very easy and save going up and down the stairs.
Specially in very Dim position.
