   Sargazo y Bienestar
   Salud mental frente al sargazo — Caribe mexicano

   Paleta: turquesa profundo de las aguas del Caribe,
   templado con ocre de arena y de sargazo seco.
   Los colores de la bandera se usan como acento medido:
   la franja tricolor bajo el encabezado, el verde para lo
   que tranquiliza y el rojo reservado a la ayuda urgente.
