Flower help!

Hi ladies, so i DIY'd mine and my daughters flower crowns, fake flowers, and will be making my bridesmaids hairpieces of the same flowers. but as i look into bouquets, i have my heart set on rich fall colours, deep reds, rich oranges and yellows, what im getting at is will it look terrible, having white and blue flower crowns but popping beautiful fall coloured bouquets? the bridesmaid dresses are Davids Bridal Steel Blue, hence why i modeled the hairpieces white and blue.. now im doubting myself should i redo the hairpieces to be coloured too? or am i way overthinking this? any guidance is appreciated, thank you!
