Luminance: This is a colour system to produce the best visual effects for the user to see. An example of one of these systems is the trichromatic system which uses the RGB scheme. Pop-out effect: This effect is when we use different colours to make us focus on one item or object on their screen making them pop out. We can accomplish this by using dull colours and then bright comes for the object that you want to pop out or different fonts etc.o Pattern: Proximity: The law of proximity dictates how the eyes process connections between elements. If we have elements close to each other in a group, these are related and will be the focus compared to aseparated element.This study source was downloaded by 100000859819779 from CourseHero.com on 01-09-2023 14:22:09 GMT -06:00https://www.coursehero.com/file/186507037/unit-23-task-2-finaldocx/Unit 23 Task 2: Fundamental principles of interface design
