Does it complement the paint colour or does it look awful? If you don't like it then paint the room or return the sofa for a new colour.

do you have the interior designing and finishes finalized? as I mentioned earlier, everything in the room has to be tied together. I cannot give you a colour for the arch if it is going to clash with the window frame job, or the cabinets or the wood. In case you don't, I can help you with that. we offer consulting services, which is basically this, the help on Houzz, in a lot more detail.

They are tiles I feel which had been fixed on top...so its difficult ot paint of tiles , just try ot polish them with a polish liquid ...if you need a different looks ,then you need to remove the existing tiles and paint whatever color you want...but for fountains and water surfaces , try ro avoid paint as the paint degrades ...

Hi,  An oversized painting / wall mural / traditional wall art (you may choose state specific on this one) should highlight the volume and height of the space. Additionally, good lighting - wall scones / chandelier will add to the beauty. Hope these tips help!  Regards Ar. Manjusha Adhav - Kamble
