A Christmas tree is an iconic symbol of the holiday season, and there are countless designs to choose from. Traditional trees are typically green and adorned with lights, tinsel, and ornaments in a variety of shapes and colors. Some modern designs feature non-traditional colors like pink or blue, while others use natural materials like pinecones and branches. Themes can range from rustic to whimsical to elegant, making it easy to find a tree that suits any style or preference.
