Como alterar a cor dos itens selecionados no LongListMultiSelector?

Question

Eu tenho uma LongList Múltiplo Seletor e deseja alterar a cor da borda no estado selecionado de phoneAccentBrush para um valor estático.

Infelizmente não consegui encontrar um itemStyle adequado.

Onde posso obter uma cópia do estilo padrão ou como posso alterar a cor?

É código aberto.Você pode abrir e editar uma cópia no Blend.

EDITADO

Desculpe, não percebi seu layout de grade.O estilo anterior era para o layout de lista do MLLS.Para alcançar o que você deseja, você precisa mudar o SelectionRectangle Traço retangular e SelectionTriangle Preenchimento de polilinha até o pincel desejado.
