   impresionlowcost — hoja de estilo base

   La paleta sale del logotipo original (impresion_low_cost_logo.pdf):
   tinta #060B10, cian #01B2F7, magenta #FB1987 y amarillo #FDD906 sobre papel.
   El logotipo es negro con perfilado blanco, asi que la web va sobre papel
   claro, como el trabajo que sale de la imprenta.
