She discovers how the most vivid blue is formed from sulphur atoms deep within the Earth&#8217;s crust and why the presence of red ochre is a key sign of life. In gold, she discovers why this most precious of metals shouldn&#8217;t even exist on the surface of the planet and in white, Helen travels to one of the hottest places on Earth to explore the role salt and water played in shaping planet Earth.<\/p>\n\n\n\n<p><div class='GTTabsNavigation' style='display:none'><span class='GTTabs_nav_next'><a href='#GTTabs_ul_16603' onClick='GTTabs_show(1,16603)'>Episode 2: <strong>Colours of Life<\/strong> &gt;&gt;<\/a><\/span><\/div><\/div>\n\n<div class='GTTabs_divs' id='GTTabs_1_16603'>\n<span class='GTTabs_titles'><b>Episode 2: <strong>Colours of Life<\/strong><\/b><\/span><\/p>\n\n\n\n<style>.embed-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } .embed-container iframe, .embed-container object, .embed-container embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }<\/style><div class=\"embed-container\"><iframe src=\"https:\/\/www.dailymotion.com\/embed\/video\/x3f0hao\" frameborder=\"0\" allowfullscreen=\"\"><\/iframe><\/div>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>The raw, early Earth had plenty of colour, but that was nothing compared with what was going to come next. That canvas was about to be painted with a vast new palette &#8211; and the source of those colours was life. Green is the colour of the natural world and yet it&#8217;s the one colour that plants have evolved not to use.<\/p>\n<p>The huge diversity of human skin tones tells the story of how humanity spread and ultimately conquered the planet. But the true masters of colour turn out to be some of the smallest and most elusive.

Helen explores what the world looks like to the birds and the bees. With the discovery of x-rays we could look inside ourselves in ways that previously had only been possible after death. Today those same x-rays allow us to examine life at the atomic level, helping to develop new drugs and better materials. Ultimately, by harnessing all the colours there are, researchers are beginning to image the human body as never before, revealing new ways to treat disease.<\/p>\n<div class='GTTabsNavigation' style='display:none'><span class='GTTabs_nav_prev'><a href='#GTTabs_ul_16603' onClick='GTTabs_show(1,16603)'>&lt;&lt; Episode 2: <strong>Colours of Life<\/strong><\/a><\/span><\/div><\/div>\n\n","protected":false},"excerpt":{"rendered":"<p>We live in a world ablaze with colour.
