the brain most quickly and easily responds to FOUR major attributes of all viewed objects:color, form, depth, movement.
COLOR
Every color use can be made with three basic, primary colors-Red, Green, 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
For printing you would use CMYK because it's more colors. On the web you would use RGB because it makes the file size smaller.
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 parts: Dots, Shapes and Lines
Dots: The dot is the simplest form that can be written. Hundereds of small dots grouped together can form complex pictures. Georges Seurat and other pointillist artist in the nineteenth century used a tecnique 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 wether straight, curved, or in combination, evoke an emotion.
Moods of a Line
1.Curved lines convey a mood of playfulness and movement.
2.If lines are thick annd dark, their message is strong and confident.
3.If lines are thin and light with a clear seperation between them, their mood s delicate, perhaps a bit timid.
SHAPES
The third type of form, shapes, is the combination of dots and lines into patterens. The three basic shapes parallelagrams, circles and triangles.
DEPTHS
If humans had only one eye and confined their visual message to drawings on the walls of caves, there would be no need for complex illustrations. But because we have 2 eyes set slightly apaprt, we naturally see in three rather than 2 dimensions.
MOVEMENT
Reconizing 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.
1.Real Movement: It is actual movement by a veiwer or by some other person or object.
2.Apparent Movement: Apparent, or illustrating, 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 designer positios elements so that the eyes move throughout the layout.
4.Implied Movement: Is a motion that a veiwer precevies in a still, sinlge image without any movement of object, image or eye. Optical or op art has been used in advertisements and in posters to achieve pulsating results. Visual vibration is the term use for the images.
