What colors to have with a blush pink dress?

Navy would be pretty, or gray. Lots of darker colors would work. Plum would be nice, brown would work too.

My colors are wine/burgundy and blush!

We're having lots of blush and soft light golds.

I saw a blush with turquoise that looked stunning!

Blush pink is gorgeous with a deep red/maroon. Accent colors that will blend seamlessly with blush are deep red, ivory, and gold.

You can go a different direction and choose navy blue, mint green, or a lilac purple. Do a google image search. Put in "blush and navy blue wedding", "blush and mint wedding", "blush and purple wedding". and "blush and red wedding". See what catches your eye.

Navy is a nice contrast but it is hard to find navy flowers. I would agree with @thecenterpieceflowers blush pink and maroon flowers with gold accents!!

Try a Google image search for "blush wedding palette." You'll have a lot of options all in one place. There are greens, blues, darker pinks and burgundy, even selections with pops of orange.

I'm a huge fan of blush and navy

This is my favorite combo, I'm a sucker for mint

My colors are navy, ivory, blush, and gold.

I love blush and navy or blush and grey.

My FH's sister just did blush, ivory and gold. I attached pictures of her centerpieces and our bouqets/dresses.

ETA: Just noticed you said fall. Her wedding was more springy, but you could do gold with a darker color (like burgundy or plum).

We did blush, gold and ivory. my bouquet was similar. The BMs had blush with a deep burgundy/maroon color.
