Does Ceremony/reception Decor Need to Match?

I don't think they need to match at all! But don't forget that when you enter the space, generally the bridesmaids and you will put your bouquet on the table, so it's right there on the head table anyway.

Also, they'll be wearing red dresses too, which will pull your theme in.

What you could do, if you hate the thought of red flowers on the tables, is use the other colours in your colour scheme - for eg, creams, whites, champagnes or whatnot, and have the same flowers as your bouquets but in those colours instead, so there's continuity but just less red.

I really wanted to have soft pinks, creams and peaches for my girls and my bouquets, for example - I like very soft, fluffy florals, but I didn't want to be super girly through the actual reception space as I worried it would end up being too much.

For the tables I wanted mostly greenery, quite masculine, herby type greenery. So, I asked my florist how to marry those two things together and we settled on using the fireplace - we'd have the herby greenery on the sides of an arrangement that builds up to something peachy, pink and cream in the middle to blend the two looks together without having those colours all over the tables and making the place look like it's been sprayed with pepto bismol, lol.

Definitely! Mine is one of my closest friends so I can talk to her about it whenever I want, but she was such a star at helping me figure out how to pull these two elements that felt like they were quite different into one cohesive look!

I think the pink/gold theme would look lovely, or maybe coral.

Also loads of tropical flowers are red, so that could work! Here are some pics I found to incorporate a bit of red while still looking 'beachy'!

I don't think they have to match.

There was a bit of a trend in higher-end weddings years ago called "progressive décor" where the ceremony was white or pastel (very light colors like soft pink, cream, etc.) and the décor got progressively bolder throughout the event - the cocktail hour would be medium colors like pink and yellow and then the reception was full-blown vivid fuchsia, red, etc.

I am personally making our ceremony and reception completely distinct décor, because each is in a different exhibit of the science museum we're having it in so the rooms themselves are completely different - the ceremony is in a space science exhibit where the room's existing décor is in blues and greys, the reception is in a fossil exhibit where the existing décor is in browns and greens. The only way to make this work is to either do all white/cream so nothing clashes with either room, or to embrace their distinct theming and just... go wild. I'm choosing the latter.

How blue is the floor? Is it like royal blue or a softer shade? While I don't think everything has to match perfectly there should be some continuity between the ceremony and reception so everything looks cohesive. I love Rosie's idea of tying in some softer colors like creams, champagnes, peachy pinks, etc. I think if you try to stick to strict red and white and have a royal blue floor, you run the risk of looking super patriotic and having your wedding feel like it's 4th of July/Independence Day themed.

You could definitely have a different theme entirely indoors, but I would just want to make sure there was something to tie together the overlapping elements. I think red bridesmaids dresses might look a little out of place at a beach themed reception unless there was some red tied into the decor/color scheme indoors as well. As long as you have some elements that make it all cohesive, it will look great!

I think you can definitely still tie the red into the reception!! Here's some different things I found featuring red and blue as the main colors. I know your bridesmaids will be wearing red, but this just gives you an idea of how the colors can work together. I hope this helps!!
