Color Addition
Color and Vision Color Addition Color perception, like sound perception , is a complex subject involving the disciplines of psychology, physiology, biology, chemistry and physics. When you look at an object and perceive a distinct color, you are not necessarily seeing a single frequency of light. Consider for instance that you are looking at a shirt and it appears purple to your eye. In such an instance, there may be several frequencies of light striking your eye with varying degrees of intensity.
Any function: y = f(x) that graphs as a straight line has an equation of this form: NOTE : This does not include vertical lines, because they are not functions of 'x': y = f(x). A function of 'x' cannot have more than one point in the same vertical line. 'Gradient ' is a number that represents the steepness of a straight line. A horizontal line has gradient zero.
y = mx + c
