Meaning of colours in psychology

After looking at the work of Catherine Yass, and realising the colours which she uses are quite calming colours, I thought it would be beneficial to look into the meaning of colours in psychology, and colour meanings.

Obviously meanings of colours can vary between circumstances and culture, and all colours have many aspects to them. There however a few connotations to each colour.

"Color is a form of non verbal communication. It is not a static energy and its meaning can change from one day to the next with any individual."

Red: is the colour of passion, or again it may mean anger.

Orange: is the colour of social communication and optimism. It is also a sign of pessimism and superficiality.

Yellow: yellow is the colour of the mind and the intellect. It is optimistic and cheerful. However it can also suggest impatience, criticism and cowardice.

Green: is the colour of balance and growth. It can mean both self-reliance as a positive and possessiveness as a negative, among many other meanings.

Blue: is the colour of trust and peace. It can suggest loyalty and integrity as well as conservatism and frigidity.

Indigo: is the colour of intuition. It can mean idealism and structure as well as ritualistic and addictive.

Purple: is the colour of the imagination. It can be creative and individual or immature and impractical.

Turquoise: the meaning is communication and clarity of mind. It can also be impractical and idealistic.

Pink: the psychology of pink is unconditional love and nurturing. Pink can also be immature, silly and girlish.

Magenta: is a colour of universal harmony and emotional balance. It is spiritual yet practical, encouraging common sense and a balances outlook on life.

Brown: is a serious, down-to-earth colour that relates to security, protection and material wealth.

Grey: is the colour of compromise - being neither black nor white, it is the transition between the two "non-colours".

Silver: has a feminine energy; it is related to the moon and the ebb and flow of the tides - it is fluid, emotional, sensitive and mysterious.

Gold: is the colour of success, achievement and triumph. Associated with abundance and prosperity, luxury and quality, prestige and sophistication. Implies affluence, material wealth and extravagance.

White: is colour at its most complete and pure, the colour of perfection. The colour meaning of white is purity, innocence, wholeness and completion.

Black: is the colour of the hidden, the secretive and the unknown, creating an air of mystery. It keeps things bottled up inside, hidden from the world.

Before reading the above named website, I did not know the meanings or connotations of most of the colours named. It has been really beneficial to me, as I can start thinking about what colours I can play with in my paintings and photography pieces, in order to unsettle the viewers of the works.
