Glossary

taxonomy

n. 1. The classification of organisms in an ordered system that indicates natural relationships. 2. The science, laws, or principles of classification; systematics. 3. Division into ordered groups or categories:

temperature, color

Color temperature takes two meanings: (1) the physical meaning, and (2) the associative meaning. We work with associative temperature. Associative temperature Cool and warm are adjectives we apply to color, and we call the relative warmth or coolness of a hue temperature. Physical coolness and warmth are haptic sensations of touch, not vision but we describe colors this way because of the learned association to physical temperature sensations. We associate blood, fire, and sunlight colors as warm colors, and plant, sky, and water colors as cool colors. Temperature groups Color temperature is a color organization criteria (cool-warm contrast). We can classify colors as 'warm' colors or 'cool' colors. Like the cardinal compass points, red/green are spectrum and temperature opposites, and blue/yellow are spectrum and temperature opposites. We associate yellow-orange through red-violet as warm, and yellow-green through blue-violet as cool. Yellow and violet shift easily between the cool and warm groups.
