Walk through closets / robes

I really want our walk through robe to be "sexy". Our walkway is not as wide as the one in the first photo below, and we are only putting in two downlights in there. There can't be a chandelier ... and due to the narrow walkway we can't really fit anything in between :(

Should we go for two different colours? Should we paint the "backing" a different colour?
What would yousuggest we do in order to make our walk through interesting? Our clothes are nowhere near as colourful and interesting as in the photos below :(

Our master bedroom, walk through robe and ensuite layout.

The wardrobe fitout so far.
