Early October colours

I think those colours would be fine for a fall wedding. We are getting married October 5th. And we originally chose teal, pewter and dusty purple (our theme is succulents) but the colours started to matter less and less and now it's just vaguely greens, teals pewter and a touch of dusty purple here and there and it's still going to be beautiful. Make yourself happy.

For our October 5th wedding we are having Teal and Plum and to bring it in to look more "fall" like we are using Copper

I say that you don't have to worry in general - but if you are then I'm sure that adding copper could help?

If you want to use those colours, do it! I'm using colours that aren't usually considered fall colours (turquoise and purple - peacock), but I like them and want to use them in our October wedding.

If you want to make your colours more "fall" like, add burgundy or dark green as an accent colour but keep your original colours the same

The colour of dusty rose would look nice with pumpkin orange and light green colour to incorporate 3 tones of palettes from light to dark. The combination may pull together to have your vision looks great.

I am getting married September 28th and my colors are dusty rose, burgundy and gold. I feel they are a nice rich color that works for fall. Michaels fall line of floral and decor has a lot of dusty rose items that are really nice. My opinion is if you love a color there is no reason you cant use it any time of year!
