¿Cómo cambiar el color de los elementos seleccionados en LongListMultiSelector?

Question

tengo una lista larga Multi Selector y desea cambiar el color del borde en el estado seleccionado de phoneAccentBrush a un valor estático.

Desafortunadamente no pude encontrar un itemStyle que se ajuste.

¿Dónde consigo una copia del estilo estándar o cómo cambio el color?

Es de código abierto.Puedes abrir y editar una copia en Blend.

Lo siento, no noté el diseño de tu cuadrícula.El estilo anterior era para el diseño de Lista de MLLS.Para lograr lo que deseas necesitas cambiar el SelectionRectangle Trazo rectangular y SelectionTriangle Rellene polilínea hasta el pincel deseado.
