The central feature is lit up like a Santa Claus in this theme while the rest of the building is an icy green. The small home fires burning are the reds in the corridors that complete the Christmas theme.

Diwali the festival of lights brings alive a thousand small lights that are identified with the festival.

For each theme the lights change gradually as in this theme for Diwali, the timings being controlled by an astronomical clock.

The colour green dominates the building for Eid and forms further variations on it.

The most dramatic theme is the Indian National Ticolour that unfurls like a flag over the building on Independence Day on August 15th and the Republic Day on 26th January.

The carefully placed lights magically bring out details that are not highlighted in the daylight.

Rudyard Kipling's father John Lockwood Kipling was the director of the JJ School of Art who was in charge of the hundreds of sculptural details that adorn the building in a fusion theme which is like a virtual jungle book in the midst of Mumbai.

Faces of famous people and commoners are lit up to bring out the human dimension of the building that is loved by all.

The church like appearance of the office building is typical of the Victorian period buildings in Mumbai designed by Fredrick William Stevens who used polychromy and a fusion of Gothic revival and Indian motifs in the design of the building.

The top-heavy architecture creates a dramatic skyline and is a delight for the 3 million Mumbaikars who love the polychromy on the building.
