While helping students understand and define color themes, the terms "warm" and cool" are often used to describe a color. In general different blues, greens and violets are considered cool colors while yellows, oranges and reds are considered warm. We associate certain feelings rather than actual temperatures. A warm yellow-orange might feel cozy like by a fire or cool blues feels calming as water by a beach. Warm colors optically tend to advance while cool colors recede. Whatever the color theory process we teach our students, they always seem to choose the one they love the most to be able to create these wonderful paintings.
