A wedding color scheme refers to the selection of colors used in a wedding event, including attire, decorations, and floral arrangements. It is a way to express the theme, style, and personal tastes of the couple. The color scheme can be coordinated around a single dominant color or a combination of colors that complement each other. It's important for the scheme to be visually appealing and harmonious, and it can also be a reflection of cultural or seasonal motifs.
