Try tying in with that beautiful piece of art we can't see hanging on your wall ! It might just be time of day,
but a splash of color will do wonders to give your room a "pick me up" !

What colors are your curtains? From the picture, looks like they could be silver sage/ blue-green. If so, I would find pillows to compliment the colors in the panels.

Walls are beige, Curtains are sea foam and sofa is blue. Maybe I need to change curtain color? Also debating paisley or chevron style for pillows... I'm confused. Thanks

I would purchase new curtains that are a print (I love paisley, so that's my vote) and then purchase pillows. The pillows need to be different size, not all that small to medium. Pillows can be expensive so you might want to look at One or two special pillows and making the rest. You can do it with hemming tape, no sewing involved.

The chevron looks best, nice contrast. You could even do the chevron plus a solid plain colour as well. Depending of you want to introduce another colour...orange, coral, or lime, gold would all work. But chevron for sure.

Colors are too hard to do on a monitor. That said, seeing the pillows close up on your sofa, I think the gray one is the only one that really works. (I could totally change my mind if I saw them in person.) The problem with the left and middle pillow is that I don't see those colors anywhere else in your room.

Try getting one pillow in the color of your curtains, another in the color of your rug and see if that feels more cohesive.
