   Paleta clara de alto contraste, pensada para lectores mayores:
   · Texto oscuro sobre fondo cálido claro. El texto claro sobre fondo
     oscuro produce halación (las letras "sangran") en ojos con cataratas
     o astigmatismo, muy frecuentes a partir de los 60.
   · Crema en lugar de blanco puro para evitar deslumbramiento.
   · Acento granate en lugar de dorado: el cristalino amarillea con la
     edad y los amarillos pierden definición. El granate se mantiene.
   · Cuerpo de texto a 19 px con interlineado 1.75.
   · Ningún texto por debajo de 7:1 de contraste (nivel AAA).
