The most perfect color combinations are subjective and can vary depending on the context. However, a popular approach is the use of complementary colors, such as blue and orange, or contrasting colors like black and white. In interior design, the 60-30-10 rule is often applied, where the main color takes up 60% of the space, the secondary color 30%, and the accent color 10%. For fashion, matching complementary colors or analogous colors that are adjacent on the color wheel can create pleasing combinations.
