Red and yellow and pink and green / purple and orange and blue / I can see a rainbow / I can see a rainbow / I can see a rainbow too! Penguin Classics may be entirely orange but Random House's Vintage Classics are an entire rainbow! Their vintage imprint has reached the ripe young age of 21, and to celebrate they've reprinted the entire collection in these amazing hues. It could take a while to collect them all but they would definitely give your bookshelf a splash of colour. The imprint includes Rushdie, Coetzee, Roth, Atwood and Murakami - heaps of our favourites. You can see the whole collection here.
