I was debating posting decorating ideas here but the principles are the same are they not? We use color, pattern, sheen, and layering to create a feel or vibe in an outfit and in a room.

So I am planning the DR decor. The room is just under 13 x
10 with a bow window facing east and an arched opening to the front
entry hall. The floors are a laminate with wide planks in a hand
scraped finish that also has a grey undertone. The rug in the picture is not staying. I plan to look for something with a geometric pattern in soft subtle color or texture.

I plan to put floor length panels in a silvery grey with vertical seams between the windows and on the ends hung on a 1" pewter rod that follows the angles
of the window. I bought 2" white faux wood blinds that will be inside
mounted. I also bought an antique crystal chandelier and a very large
mirror with beveled frame. This should add texture, sheen, and the jewellery or sparkle.

I had initially planned to paint the walls with CIL Wexford Fog (green grey) with a soft metallic stencil in a circle or geometric pattern. The mirror would hang on the long wall and would reflect the chandelier back into the room and hall. I brought home fabric samples and am now considering using Rose Stone or BM elephant grey - both mauve pink that are greyed down. I will use a metallic paint to mimic wallpaper on the long wall opposite the entry.

I am attaching pics of the chandelier, mirror and room with one of the fabric
for the chairs draped on a chair with the window panel over the back. The fabric has a silvery white floral pattern that I thought added a bit of old world elegance. I put the paint chips on the seat. The pics are in front of the window in late afternoon light. I am going for a bit of 20s glam look with
sparkle and shine but soft colors. The darkest color showing on the middle chip is the Rose Stone that I am leaning towards.

As a bit more info, I am considering using the Wexford Fog in the MBR and the Rose Stone in the ensuite and have deep blue/teal fabric in the great room and dinette area. I lean towards cool colors in general.

What do you think of the color plan? Any other suggestions?
