I think you need to post some photos. It's very hard to picture what you have, or what it is you're looking for, without some visuals to help.

I don't think aqua is a good choice.

On this link, scroll down to the section on Color Harmonies. Your current pillows, for example, are a triadic color scheme with the 3 secondary colors green, purple and orange (rust). I don't see a color scheme where the aqua would look good with your green and purple.

For better suggestions, show us pictures of the 4 walls of the room, and the furniture you are keeping. What color are your walls? Is new paint in the budget? It might have a bigger impact than throw pillows.

You might get some ideas from this search The green and eggplant could be very sophisticated.

Thank you all for your helpful replies. Not at home to shoot the furniture and walls but did just find this fabric at a local store. The background is the exact eggplant color of ottoman and drape panels. The green fern works with the olive green couch. I was thinking I could use some aqua prints

to lighten things up. Would that bring my living room into the modern world?

Got to have photos of the room, but what might work is that pale blue/gray in the fabric above.

Aqua is not going to work with olive and eggplant, but the good news is that olive and eggplant are not "dated" colors on their own - it is only your usage of them. If you post photos you can get suggestions to update the space. It may be paint, artwork, adding a few new updated accessories, or just removing items from the space.

IdaClaire- I love that print and that is exactly what I imagined - but could not find. Do you know its name? It might be too bold for the room, but I’d love to get a sample. Muted could be the way to go but worth seeing both options in person. (The couch is actually a sofa and loveseat. That and the purple ottoman are it for the furniture In the room. )

Please consider repainting the walls....that is your largest expanse of the jewel tone colors you want to update. Choose your fabric before you choose wall color. The fabric sample from IdaClaire is a great choice; brighter, younger and more current than your choice. The white background would be good for wall paint.

Without photos of the room, we're all just guessing.

A fabric may give you a jumping off point but getting the space to what you truly want will likely take a bit more. Buying new covers for the pillows and changing the drapes is probably a good guess, but hard to say without pics of the space.& again,what colour is on the walls?

Pictures are going to be the best IMO the drapes need to go that color is done and then some. I think the sofa can be made to work but we need pictures

You can add a bit of aqua very nicely with the pieces you have :)

Still no pictures of the room?

Our color palette. Sofa/loveseat is green. Panels are purple as is the ottoman The whole house was painted last year (Dunn Edwards Bone) and carpet was put in right after that. All the trim and doors are pure white. The downstairs is all open concept. I do not want to repaint. Replacing drapes, buying new artwork and reupholstering any of the furniture is not in the budget. What I would like to do is add a bit of interest by introducing a new color to use in throw pillows and blanket. I thought it would be simple. It’s not! I appreciate the samples many have provided. I guess the bone wall color might preclude using a white background fabric (?). The fabric I posted, while the colors are right, seems a bit bland. Just looking for suggestions for a fabric that will work. No energy (or money ) to redo much else.

A white fabric background is fine with the bone walls just like your white trim is good. Actually, pillows and blankets with the white background would lend to the brightness you're looking for. I love the fabric IdaClaire posted. Look for accents like that! I personally don't think your green and eggplant colors are dated. They're more classic to me.

I love the fabric IdaClaire posted too. I would love to get a sample. I definitely feel like it would brighten up the room while allowing me to keep what I have. I hope IdaClaire comes back to share that info.

It looks like IdaClaire's suggestion could be an area rug. rug

)-: Well at least I won’t spin my wheels looking for this fabric. Wish I had a spot for the rug.

This P Kaufmaann print is beautiful and fresh.

I love your present color scheme. I think the pillows you have are bolder than the one IdaClaire suggested. Did you take a sample of your fabrics to the store because there is no way you can be sure of a match without a direct comparison. What I see on my monitor for the green couch I would never describe as olive green. White curtains would be a bright, fresh look for summer with some white vases on the mantle.
