   Trama Pisos · protótipo

   Concreto e verde. Base grafite (cor de concreto molhado),
   seções claras cor de concreto seco e o verde-limão (#C8FF3D,
   o mesmo da RF Digital) na ação e nos destaques.
   O 3D fica num canvas fixo atrás do topo, do simulador de cor e
   das camadas; depois disso as seções cobrem o canvas.
