   Thesis: the principal asks one question all day — is there room? So the week
   is the hero, drawn as a week. The 5×7 capacity grid is the signature, and it
   holds the ONLY colour in the product. Everything else is ink on paper plus a
   single primary. If something is green, amber or rose, it is telling you about
   capacity. Nothing decorative is ever allowed those hues.
