I need a blue for an East facing room?

[bignamechangeroonie]

It's a bathroom, decent size (14ft by 12ft). I'm then going to put a giant wallpaper map on the main wall, lots of blues.

It's light in the morning but not massively so, window is frosted so not that bright.

I suspect I need a non muddy blue so not duck egg, no deep undertones but something clear and bright ?

My east facing kitchen is painted in Light Blue (F&B) and I love it. It changes from blue to grey to green depending on the time of day and the weather. I got the room repainted last year in the same colour because I love it so much.
