I probably wouldn't use RH for paint, there just aren't as many options. I like the color you have now more than the two they suggested. Those would just turn your room into a brown blob.

As an alternative, you might want to consider something new and striking such
as 3D wall panels, textured wall paper or adhesive wall tiles. They can add a
dramatic, yet subtle effect with dimension to your room that doesn’t cost a lot
and is easy to install. Check out some ideas here: https://www.houzz.com/projects/1258135/wall-decor

I really like what you already have as well. Beautiful, sophisticated, elegant.

HI -- The color you have is lovely , and if you have more of it then also paint the ceiling the same .It is a nice look for a bedroom. The RH paints are great and there is a reason for the limited colors . The colors are more muted and too many colors make choices hard for most people . The RH colors are to complement with their line of furniture . I personally use Benjamin Moore Paints or Valspar . Sherwin Williams paints are also good . If you have a bedspread or bedding set , then get your color from that . But keep the room color soft and muted and like I said before do walls and the ceiling all the same .
