   Fİ ERP — Tanıtım sitesi
   fierp.fidata.tr

   KARAR: Kahraman görsel, soyut bir çizim ya da büyük bir rakam değil;
   ürünün KENDİ ÇIKTISI — dizilmiş bir fatura. Muhasebe yazılımı satan
   bir sayfada en ikna edici şey, programın ürettiği belgenin nasıl
   göründüğüdür. Lacivert zemin üzerinde masaya konmuş bir kâğıt gibi
   duruyor; panelin "cetvelli sayfa" dili burada da sürüyor.

   Zemin fidata.tr'nin lacivertinden (#070b16) geliyor, panel ise
   açık. Bu ayrım bilinçli: tanıtım sayfası bir kez okunur ve etki
   bırakmalı, panel sekiz saat kullanılır ve yormamalı.
