That shower curtain is pretty intense. Are you sure you want to keep it? It's just a little "precious" for older girls with that much pink, IMHO. The only color that I think could stand up to it with older girls would be a pretty bright orange, and try for a Morroccan casbah look with even more pattern and color and brass hanging lanterns and screens. Layer a cobalt blue curtain under the pink and use some metallic chains for the tieback for the pink curtain. Paint the ceiling turquoise. You can get some talavera or Turkish tiles on Ebay and frame them for an accent. If you have a drop in sink, you could replace it with a talavera one. They aren't that expensive and give lots of style. Cobalt blue bath accessories and rug with other hints of turquoise and pink here and there and it would be fab. As an alternqative, I could definately see doing a fun apple green and white bathroom, but not with that curtain. For green and white, use the chair rail/wainscoating approach and put the green below with white above. A fresh gingham check or ticking stripe for the shower curtain and add in more color with different shades of green towels. A dark green rug and various green accessories would complete the look.

Very pretty bedding! In the most current Fall/Winter PB Kids catalog there is a girls nursery done in a beautiful shade of clear crisp blue. It may be BM Antiguan Sky 2040-60 - I don't have my catalog w/ me. I'm just thinking how pretty a delicate crsip blue would be w/ those colors. I just got done painting a piece of furniture SW Buoyant Blue. When I saw the color on the chip I wasn't sure. Even though it was the lightest color on the strip it appeared crazy bright but I followed through and am so happy that I did.

How about a soft white or cream? it would keep it light and bright while you use other colors. I think pink and mustard would be a fresh color scheme with white walls and would work with gray Pink and green is also another fun, unexpected color combo with keeping with the nature theme. I know you said you don't want pink but a very light pink (almost white) can read as a neutral.

It might be, aes107. Bring home a paint chip and you'll see right away. May I suggest you try whatever colours you're considering on boards in different light to figure out what suits you best? I really like the idea of a warm white for a nursery. One of the prettiest nurseries I've ever seen was a white one posted here.
