Robin's egg color, but much lighter. Then put white iris in vases. Beautiful.

Blues with dark brown screams Grandma to me, but I'm probably biased since my own had this color scheme.
Would you consider orange? Not pumpkin or loud or gawdy, but a nice subtle mature classy looking orange?

I have links saved on my computer at home with some examples of stunning oranges that the average person wouldn't think of as a wall color but once you see the pics they're quite adorable. Sherwin William has some nice subtle orange colors if you want to take a look at their color palette. It would also brighten up the room nicely.
