Not to muddy the waters but I was wondering if you went even lighter than the pink, for example, maybe a white tone on tone or something like that, if it would make more of a pleasing contrast. Or maybe a light green tone on tone.
It's a little tricky because our screens are not always true to color. A friend of mine takes black and white photos with her phone or tablet to check on the range of colors and contrast. She swears by that. Maybe you could try that.
