Arch Shades Help Choosing Color(s) For A Great Room / Kitchen Combo?

Help choosing color(s) for a great room / kitchen combo? - arch shades

I moved into a house with 25 large 25 large rooms, open to the kitchen. Carpeting in the room is light brown. s walls are now cream and brick fireplace with a tinge taracotta (red brick s)

the kitchen is the same color taracotta kitchen vaults and safes are also color-taracotta

I want to 2 of color that work well together because the rooms are open to other possible to do justice, and I think with the same color is a bit much. Maybe an accent wall in the great room and a little lighter shade on the other walls, but have no inspiration. It cornice boards in the room that can cover any type of tissue, and yes my bed and love are put in chocolate brown (sweade microphone.

Thank you in advance for any help or suggestions
