Question 5
|
Which of the following color models are defined with three primary colors ?
|
RGB and HSV color models
|
|
|
CMY and HSV color models
|
|
|
HSV and HLS color models
|
|
|
RGB and CMY color models

Question 5 Explanation:
Common color models defined with three primary colors are the RGB and CMY models.
RGB: color scheme is an additive model. Intensities of the primary colors are added to produce other colors. Each color point within the bounds of the cube can be represented as a triple (R, G, B), where values for R, G, and B are assigned in the range from 0 to 1. Thus, a color C, is expressed in RGB components as
C = RR + GG + BB
CMY: A color model defined with the primary colors cyan, magenta, and yellow (CMY)
is useful for describing color output to hard-copy devices. We can express the conversion from an RGB representation to a CMY representation with the matrix transformation:
