VISUAL AESTHETICS USING VALUE
Value is the lightness or darkness of a colour. Every colour has a corresponding value and that lightness or darkness depends on the amount of lighting applied to the colour. The three important rules of value are: a) it controls focal points – usually the brightest area, the highest contrast, or when a predominant value encloses an opposite value; b) value gives the illusion of three-dimensional form, when it shows the surface being hit by light and the surface under the shadows; c) value creates the illusion of depth (altering the range of dark and light creates distance).
The perception of mood or emotion of the story being told in the canvas is established by the applied lighting translated into values. The success of colour composition depends on the value composition.
