Complementary colors are pairs of colors that, when combined in the right proportions, will produce white or black. They lie opposite each other on the color wheel, and when placed next to each other, these colors create the strongest contrast and reinforce one other. When using subtractive colors, the complementary color pairs are red and green, yellow and violet, and blue and orange. When using additive colors, the complementary color pairs are red and cyan, green and magenta, and blue and yellow. In interior design, when creating a complementary color palette, look beyond the primary colors and use a color scheme with natural shades like sage green, dark olive, and mustard yellow for a sophisticated vibe.
