Term
| Young-Helmholtz trichromatic color theory |
|
Definition
| the color we see depends on the mix of signals from 3 types of cones: red, blue and green |
|
|
Term
|
Definition

Term
| opponent process color theory |
|
Definition
| we see colors in set of colors known as "opponent colors" : red-gree, yellow-blue, white-black |
|
|
Term
|
Definition
a meaningfully organized whole.
Principles:
- figure-ground: the eye differentiates an object from its background.
-similarity: when object look similar, we tend to perceive them as a group.
-proximity: when objects are grouped close together, we tend to perceive them as a group.
-continuity: the tendency for our eyes to move through one object and continue to another.
-closure: when an object is incompletely closed, we perceive it differently by filling in the missing space |
