Turquoise blue seems to be the trend with brown these days

It entirely depends on the mood you want the quilt to have.

Brown, pink, and yellow would be a soft, warm, calm analogous scheme (colors next to each other on the color wheel). Brown is actually just a saturated orange.

Brown, pink and green would be a more contrasting complementary scheme (colors opposite each other on the color wheel) which has added zip.

Brown, pink, and turquoise is straight from the 50's and would give the quilt a very retro feel.

Next time i have a color question - i'm PMing you ghostrider !!!!! Your analysis was perfect !
That said...my choice would be turquoise.

lime greens is a good choice. or turquoise. I love lime green. just found a UFO top and it has a lime border already. I like it, so i may finish it!

Thanks everyone...I just bought some lime green and I am not sure it is going to work but if it doesn't, then I will use the turquoise. I am not good at posting pictures but I will try again when this quilt is finished. Thanks again. These board members are sooooo helpful.

I think orange would be a good color. But of course a pic of the pattern and fabrics would help with suggestions.

i think lime would work really well

How about hot pink?

Maybe even a brighter pink as a third color.

A rich teal color would be really pretty and make your quilt pop!
