Choosing your color can depend on how often the color will show up in your decor and wardrobe. Ask yourself ~ will they be a primary part of all my decorations or just a secondary color I use when selecting napkins and / or favors. This may help you decide how vibrant or deep the color should.
What season are those bells ringing? You may want to march to the same beat of the season or choose a color that works well with the outdoor setting of the seasonal backdrop. Fall weddings, for example, are made even more vibrant by colors that naturally occur in that season, like deep reds or oranges, while spring weddings most often lend themselves to brighter palettes.
Are you planning a wedding that has a more intimate and calm feel to it? You may want to go with lighter and warmer colors than a wedding that's more outdoors or has a summer or spring vibe to it.
A color wheel tool is always a great option to refer to. Pairing colors together helps you to see them side by side to ensure they compliment each other, don't compete and also truly just feel right together.
If you already have your mind made up that you want a full red bouquet of flowers and centerpieces, then you may want to start there and plan around this color first.
Is this overwhelming? Shake it off. Don't overthink this stuff. Pick one or two that you enjoy and incorporate them in your special day where you feel it is right. That simple.
