Wedding colors

My colors are dusty blue, dusty pink and dusty purple. I have 3 bridesmaids and they will each be wearing one of the colors. I wanted my flower girls to wear the pink n purple to match the bridesmaid (ring bearer will wear the blue) but having a hard time finding one's that match. I realized yesterday my shoes, and wedding invitations are more of a blush than dusty pink. I'm wondering if I should change my colors to the lighter shades? I didn't want them light since I'm having a Fall wedding. Or does it matter I have different shades of pink? It's hard to imagine how everything will look together.
