Read a book with each colour IN THE TITLE. For the "variant" prompts, you can choose either a shade of that colour or a word commonly associated with that colour (examples have been provided). This challenge does not have a start or end date.

PLEASE NOTE: This challenge is NOT intended for the colours of book covers. Please only add books with the prompted colour IN THE TITLE. Books in languages other than English are more than welcome as long as the colour is IN THE TITLE.
