Color for the Bedroom

Window renovation done and in the process the walls have been slightly damaged and needs re-painting which is both good and bad news, bad news as they were very recently decorated and good news as I can try a new color. I tent to do feature walls rather then the whole bedroom, which means bolder colors can be used. Might be a bit old fashion and naughties but I think it works very well. Question is how to choose the color... muted blues and green is usually a good choice for serenity but our west facing room requires something stronger.  Thinking taupe or dark navy blue. Both of the pictures below are Pottery Barn & Benjamin Moore.
