You have two options: have your curtain panels be neutral for a monochromatic theme or pick patterned panels which have the colors in your accent pillows etc.

I would suggest you purchase several options, making sure you can return everything with no problem. When you hang up each option, you will know which one you like the best!

Thoughts?

Good advice from visualizemaven. We cannot see colors because the picture is dark.

Here's a better photo. Thank you!

Thank you for the clearer photo.

Well you might not want to hear this but........Your area rug is too small. It really needs to extend to well under the chair section of your sofa and at least 1/2 way under your blue chair.

Right now the only orange you have happening in the room is that pillow. If you want to introduce more orange, search for a patterned curtain panel which has oranges, blues, grays and yellows/creams. But that will be difficult to coordinate with existing rug which I think may have to go anyway due to size.

Think about a natural or f aux sisal area rug. Introducing texture and natural elements will enhance your room. It will also give you flexibility in your curtain style/color/pattern.
