What The Brain Sees

The brain most quickly and easily responds to FOUR major attributes of all viewed objects : color, form, depth and movement.

COLOR
Every color we see can be made with three basic, primary colors - Red Green and Blue AKA RGB.

Secondary colors in light are formed when 2 primary colors are mixed together. When mixed equally, red and blue light will make magenta. Green and red will make yellow. Blue and green will create cyan AKA CMYK.
EXTRA CREDIT: I would use CMYK for printer purposes will make more vibrant because it's more color. RGB will be used for the web so you file will be smaller because it's less color.

FORM
Another common attribute of images that the brain responds to is the recognition of form. Form defines the outside edges and internal parts of an object and has three parts: Dots, Shapes, Lines.
*DOTS: the dot is the simplest form that can be written. Hundreds of small dots grouped together can form complex pictures. Georges Seurat and small other pointillist artist in the nineteenth century used a technique called pointillism.

* LINES
When dots of the same size are drawn so closely together that there is no space between them, the result is a line. Lines whether straight, curved or in combination, evoke an emotion.
moods of lines
1. Curved lines convey a mood of playfulness and movement
2. If lines are thick and dark, their message is strong and confident.
3. if lines are thin and light with a color 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 parallelograms, circles and triangles.

DEPTH
If humans had only one eye and confined their visual messages to drawings on the walls of caves, there would be no need for complex illistrations.
but because we have two eyes set slightly apart, we naturally see in three rather than 2 dimensions.

MOVEMENT
Recognizing movement is one of the most important traits of survival of an animal. There are four types of movement, real, apparent, graphic, and implied.
1. real Movement: It is actual movement by a veiwer or by some other person or object.
2. Apparent Movement: Apparent, or illusionary, movement is a type of motion in which stationary objects appear to move. The most common example of this type of movement is a flip book.
3.Graphic Movement: can be the motion of the eyes as they scan an area or the way a graphic design positions elements so that the eyes move through out the layout.
4. Implied movement: is a motion that a veiwer perceives in a still, single image w/o any movement of the object, image oor eye. The most common example of this type of movement is called optical or opt art
