Semiotic Theory

The semiotic theory was created by Saussure. It uses signs and colours to signify the meaning of something. For example a red rose signifys love because of the colour red. Also the yellow of the sun. Yellow is a bright, pastell colour which signifys happiness and brightness.

For example:
The colour Red signifys anger, love, romance, lust.
The colour Grey signifys rain, clouds, depression.
The sun signifys warmth, happiness, brightness, the colour yellow.
