Sashing or some other addition of a little black would brighten up your colors.

I'd try a turquoise, or some other blue/green~~

This was exactly my thought...

I think your best bet is to take your fabrics to the store and see what works. You might be surprised. A soft, muted coral might even work.

I think it also depends on your pattern. The three fabrics are close in value. So if you are going to use a pattern that needs a different value to make the pattern show you should look for that value. Seems these are all medium so I would pick a dark and a light fabric.

my thoughts too--needs a blue or a violet to perk it up

Exactly what I was thinking.

I would look at green or blue, colours in nature.

Agree with many postings about adding a pop of color... but it depends on what look you want to achieve. I also think teal, purple or some variation would be pretty... it depends on how much of another color you are adding and which is your focus fabric.

I have seen several quilts lately that incorporate yellow and gray and are very lovely. You have more than one shades if yellow so you could incorporate more than one shade of gray and even white-even a smattering of black. Good luck with your choice and please show us the result.
