   Telden Şarkıya — görsel sistem: "seafoam ve gülağacı"
   Eski gitarların nitro cilalı seafoam yeşili gövdesi üstünde koyu gülağacı klavye.
   Sayfa açık ve sakin; bütün zenginlik klavyede: nikel perdeler, sedef işaretler, kemik eşik.
   Renk kodu bütün sitede aynıdır (bkz. js/lib.js):
     kök altın · üçlü mavi-yeşil · beşli mor · yedili kadife kırmızısı
     sol el 1 kobalt · 2 yeşil · 3 turuncu · 4 pembe (dolu daire + rakam)
     sağ el p i m a pastel (içi boş halka + harf)
