I recall again this topic. Maybe you have asked yourself: where is the "colour song" that every Coldplay album seems to have? Every Coldplay album has a song with a colour in its title, but Ghost Stories hasn't. Or maybe it has but it is "hidden"? I mean, I think that all the Ghost Stories theme is dedicated to one colour. And that colour is blue. My theory is that everything under Ghost Stories is linked to this colour. It is known that blue is a colour related to sadness, and GS is a breakup album. It is like Picasso's blue period, where lots of pictures were painted with those serious blue tones. The cover itself is all blue, with the sky and the sea, things that represent that colour. And furthermore, the picture also is in a moment of the day that represents the blue (Midnight). And sometimes we have speculated about the possibility of Midnight being the "colour song", so at least it would be something to consider. And to end up, they also have been wearing lots of blue clothes during the GS era. So there is no doubt, GS is "into the blue"!
