Yes, it would work. Since you're putting it on the ceiling, you want to go with a brighter, more vivid pink than you'd think. Assuming you mean Sherwin-Williams Snowbound. Sherwin Williams is super short in the pale pink paint colors department. They had several in their old, black Color Specifier fandeck. But they changed bases which means several colors in that older fandeck can no longer be made. To complicate things even more there are colors in the old fandeck that CAN still be mixed but they no longer have chips in the stores. So, if you want a pink from SW you're going to have to ask at the counter if they have an old Color Specifier fandeck so you can see a chip. They can still make these three pinks: SW7108 Pink Vibernum, SW 7110 Cosmetic Blush and SW 7111 Laurel Pink. Whether they have the old fandeck or not, they can still make Color To Go samples jugs. But that's kinda risky... to buy a sample with out a target color chip for them to mix to and for you to check and compare.

Color of white that are whiter than Snowbound: Behr's Ultra Pure White Benjamin Moore OC-151 White And you have to buy these colors in their home brand - another brand can't match them. There isn't another color from SW that would show up as whiter than Snowbound. These two might not either even tho they are technically whiter than Snowbound.

What did you decide and how did it turn out? I am in a similar dilemma, but with Agreeable Gray in the well-lit open spaces. It looks so dingy and lifeless in the north-facing bedrooms. I'm leaning now towards just using dark and moody colors.

I would pick SW alabaster with BM Edgecomb Gray. These two colors complement each other beautifully. SW snowbound has pink undertones. Another white that I would suggest is SW pure white.
