Wedding Color Palette: Teal + Mint (a color palette in tones of teal and mint). Two of my favorites on the cool end of the color spectrum, and they pair beautifully simply with each other or with accents of cream, blush, or lavender. This color palette looks lovely with bridesmaid dresses in watercolor shades of sea glass mint, peacock teal, and misty grey-green (think dusty miller). These colors are naturally soothing and relaxing to look at.
Perfect for a teal and mint wedding. Get inspired by this gorgeous ocean color palette featuring stunning shades of green and blue.
