Complementary And Adjacent Colors

There are two types of relationships between colors in the color wheel: complementary and adjacent. Two colors are complementary when they are located opposite each other in the circle - green and red, blue and orange, yellow and violet. Adjacent colors are those found next to each other - red and orange, yellow and green, and so on. These two relationships are the foundation for mixing colors; that is, they tell us how to change the color hue, making it darker or grayer.
