Triadic color schemes incorporates three hues that are evenly spaced around the color wheel. This means you’re drawing colors from both the cool and warm palettes and working with dynamic contrasts. A color wheel is made up of three kinds of colors, namely, primary, secondary, and tertiary. Primary colors are those which cannot be created from other colors, such as red, yellow, and blue. Secondary colors are those which are created by mixing two primary colors, such as orange, made by mixing red and yellow; violet, made by mixing blue and red; or green, made by mixing yellow and blue. Tertiary colors are those that are created by mixing primary and secondary colors, such as yellow-orange, red-violet, blue-green, blue-violet, yellow-green, and so on. Besides these, there are a number of other color schemes, as well, such as monochromatic, complementary, analogous, split-complementary, contrast, double contrast, and tetradic. All these color schemes are created by combining colors belonging to the three color groups from which a color wheel is made: Primary, secondary, and tertiary.
Triadic color schemes are created by using three colors that are spaced out equally on the color wheel. This color scheme provides the right visual contrast, yet maintains a kind of harmony, making the color combination look good and unique. Although they do not provide as much contrast as a complementary color scheme would, it still retains balance, making the colors look rich. That is why we see many interior designers and wedding planners these days experimenting with tricolored triadic schemes.
