Plutchik's emotion wheel. A model of human emotions for machines.

The wheel of emotion was invented by Robert Plutchik to defines a model of human emotions and their relations and combinations. It consists of 8 basic emotions, opposed in pairs, and multiple shades.

The model resulted in a circumplex where emotions and variations are represented by different colors and hues. This circumplex can be flattened in a 2D view (see below) to allow viewing of all emotions at once.
