What the brain sees

the brain most quickly and easily responds to four major attributes of all viewed object: color , form,dept and movement.

1. COLOR:every color we see can be made of three basic primary colors-RED, GREEN and BLUE.

2. Secondary colors in light are formed when TWO primary colors are mixed together.
red and blue light will make magenta, red and green will make yellow , green and blue will create cyan AKA CMYK.
If you are printing which would you use? secondary. because you have more colors to work with.R.G.B red . green . blue.
when making things for the web. Primary colors because it will make your file smaller

1. FORM: Another common attribute of images that the brain responds to is the recognition of the form. Form defines the outside edges and internal parts of an objects and has the parts dot,shapes and lines

DOTS: is the simplest form that can be written hundreds of small dots put together can form complex pictures .georges seurat and other pointillist artist in the nine rearth century used a technique called pointillism.

LINE-when dots of the same size are drawn so closely that there is no space between them ,the results is a line. Lines whether straight ,curve or in combination ,evoke an emotion.

3. If line are thin and light with a clear separation between them , their mood is delicate perhaps a bit timid

SHAPES:The third type of form shapes is the combination of dots and lines into patterns the three basic shapes are parallelagrams ,circle , and triangle.

DEPTH:If humans had only one eye and confined their visual messages to drawing on the walls of carves the would be no need for complex illustrations.
But because we have 2 eyes set slightly apart we naturally see in three rather than 2 dimensions .

MOVEMENT: Recognizing movement is one of the most important traits in the survival of an animal. There are four types of movement real apparent graphic and implied.

The most common example of this type of movement is called optical art op art.
