A.B.
We moved into our new house in April and I chose what sounds like a similar color for our master bedroom. The painter called me into the room as soon as he had about 1/2 a wall done to ask me if the color was right. It was. My husband (who had nothing to do with the color choice) was kind of surprised by the color as well. It is a beautiful spring green - very bright. When the drapes went up and the furniture was moved into the room and pictures went up on the walls the color seemed much more muted. I was happy with the color with nothing in the room but my husband liked it when the furniture and fabrics came into the room - not so much when the room was empty. So, if you can put your stuff back into the room and see if that kind of softens the paint color, I would suggest doing so.
Good luck!
