   PALETA: base de MARRONES (tierra/montaña) + acento VERDE BOSQUE.
   Se eligió el verde frente al terracota porque sobre una base marrón el
   terracota queda monocromo y apagado; el verde da contraste, enlaza con el
   escudo del club (campo verde) y resulta más elegante. El ocre se reserva
   como acento puntual (destacados, subrayados, medallas).
