Frequency reflected back from surface is decide the color we see and this frequency is called as:
a) Dominant frequency
b) Color frequency
c) Hue
d) A and C both
------------- is the radiant energy emitted per unit time, per unit solid angle and per unit projected area of the source.
a) a) Dominant frequency
b) Intensity
c) Hue
d) Purity
-------- of the light describes how washed out or how “pure” the color of the light appears.
a) Purity
b) Saturation
c) A and B both
d) Dominant frequency
-----------both collectively refer as chromaticity.
a) Dominant frequency and purity
b) Purity and saturation
c) Brightness and purity
d) Brightness and hue
If two color source combined to produce white light they are called:
a) Supplementary colors
b) Complementary colors
c) Primary colors
d) None of these
Typical color models that are used to describe the combination of light in terms of dominant frequency use three colors to obtain reasonable wide range of colors, called :
a) Dominant wavelength
b) Chromaticity
c) Color gamut
d) Saturation triangle
