The natural world is full of colours. For us, they are a source of beauty, but for animals they are a tool for survival. David Attenborough reveals the extraordinary ways in which animals use colour: to win a mate, to fight off rivals and to warn enemies. New camera technologies - some developed especially for this series – also allow us to see colours and patterns usually invisible to human eyes.
Ultraviolet cameras reveal bright signals on a butterfly’s wings and facial markings on yellow damselfish that are used as secret communication channels. Some animals can also detect polarized light, and specialist cameras can now show us how fiddler crabs see the world, and how mantis shrimp have strange polarization patterns on their bodies to signal to a mate or rival.

From space, Earth is a kaleidoscope. Turquoise plankton blooms trigger a feeding frenzy, China turns yellow with rapeseed flowers, and mysterious green lights appear in the ocean. Satellites give us a new perspective on its greatest and most beautiful spectacles allowing us to make new discoveries We can watch landscapes change through the seasons and marvel in the scale of their transformations.
Satellite cameras capture a kaleidoscope of extraordinary colours surprising and constantly changing, created by natural phenomena, by animals and by people. These colours are revealing new insight into the health of our fragile planet, transforming our understanding of our colourful home.

Artists, academics, and critics discuss the historical origins, original reception, and slow climb to critical acclaim for Eugene Delacroix's painting commemorating the Revolution of 1830, 'Liberty Leading the People.'
A woman of the people with a phrygian cap personifying the concept of Liberty leads the people forward over a barricade and the bodies of the fallen, holding the flag of the French Revolution – the tricolour, which again became France's national flag after these events – in one hand and brandishing a bayonetted musket with the other. The figure of Liberty is also viewed as a symbol of France and the French Republic known as Marianne.

David Attenborough reveals the surprising truth about the cold-blooded lives of reptiles and amphibians. These animals are as dramatic in combat, as colourful in their communication and as tender in their parental care as any other animals. Join giant courting crocodiles, jousting tortoises and bright red sumo-wrestling frogs in their sophisticated, solar-powered lives.

Japan's role in World War II gets a whole new perspective in this consisting entirely of full colour footage, including colour films from Japan that were recently discovered.

For the first time, you will see dramatic moments of WWII that were captured in 3D with stereographs and then shuttered away in secret archives and attics, until now. This stunning collection of colour 3D photos includes Allied reconnaissance photos, a trove of images that documents the rise and fall of the Third Reich, and photos secretly taken by a civilian in occupied France. WWII IN 3D also features an actual 3D motion picture film shot by the Nazis in 1943 and creates a fully immersive, three dimensional portrait of history's largest and bloodiest conflict.
