Painting the ensuite

I was suuuuuper excited when I got a pair of white tramp art mirrors for the girls' bathroom, and for a steal.  But, naturally, these mirror were just a touch shorter than the old ones, leaving a bunch of big old holes in the walls.  Which means I need to paint.  Which dominoes into the sink skirts and the shower curtain and who knows what else.

As it turns out, my girls have opinions.  Specifically, they have opinions about what color we should paint their bathroom.  Clio would like either "swimming pool" (I mentioned I had two leftover samples we could try, "swimming" and "pool."  Naturally she thinks we should mix them because the names go so well together.)  Otherwise, she wants golden honey.  Eleri thinks we should paint a silvery grey, which would actually be very pretty with the marble tile floor, but I'm not sure I want to go for a pink and grey combo (their room is pink.)

Just to get the ball rolling (and in the name of no turning back), I threw some samples on the wall--colors in the general direction that we are discussing, but probably not the perfect color themselves.

You mostly see this color form in the girls room, but you can also see it from the hallway if you look in.  In these photos, I kind of like the intensity of that chartreuse (currently in the hallway, but also changing....).  But in person, I think the softer yellowy green (which is not reading very green here) might be better.  I just worry about a rainbow sherbert situation.....

What do you think?
