   Konsepti: järvi yöllä. Syvä petroli pohjana, jäinen sininen ja koivun valkoinen
   tekstinä, hillitty turkoosi korostuksena. Lämmin meripihka vain lämpötiloille,
   huurteen sininen jäille. Editorial serif nimille, selkeä sans datalle.
   Rakenne: osiot erottuvat sävynvaihdoksilla ja vesirajaviivoilla, ei laatikoilla.
