Using complementary cardstock colors with die cuts is a simple way to create eye-catching craft projects. Complementary colors are shades that sit opposite each other on the color wheel, such as purple and yellow or blue and orange. When paired together, they bring out the best in each other, making die cut shapes look more vibrant and defined. For example, a bright orange pumpkin die cut layered on deep blue cardstock creates a bold Halloween effect, while soft green leaves on a pink background give a fresh spring look. Cardstock works perfectly for this technique because of its strength, smooth finish, and wide range of shades. Whether for cards, scrapbook pages, or party décor, mixing complementary colors helps die cuts shine and gives every project a polished, professional feel.
