The colour wheel theory of love is an idea created by the Canadian psychologist John Alan Lee that describes six love:
Eros - Eros is the Greek term for romantic, passionate, or sexual love, from which the term erotic is derived. Describes as a passionate physical and emotional love feeling of wanting to satisfy, create sexual contentment, security, and aesthetic enjoyment for each other. Catalyst - Body
Ludus - Ludus means "game" or "school" in Latin. The term is used to describe those who see love as a desire to want to have fun with each other, to do activities indoor and outdoor, tease, indulge, and play harmless pranks on each other. Catalyst - Emotion
Storge - Storge is the Greek term for familial love. Storge is defined as growing slowly out of friendship and based more on similar interests and a commitment to one another rather than on passion. Catalyst - Memories
Mania - Mania is derived from the Ancient Greek term, meaning "mental disorder", from which the term "manic" is derived. Defined as flowing out of a desire to hold one's partner in high esteem and wanting to love and be loved in this way, seeing specialness in the interaction. This type of love tends to lead a partner into a type of madness and obsessiveness. Catalyst - Survival
Agape - Agape is derived from Ancient Greek term for altruistic love. Described as an altruistic love, given by the lover who sees it as his obligation without expecting reciprocity. Agapic lovers are usually older and more emotionally mature, thus a love guided by will and reason than emotion or attraction. Catalyst - Spirit
Pragma - Pragma comes from the Ancient Greek term, meaning 'businesslike', from which terms like pragmatic are derived. Defined as the most practical type of love, not necessarily derived out of true romantic love. Rather, pragma is a convenient type of love. Catalyst - Mind
