The "hue" is the colour, independent of brightness and how much pure white has been added to it. We can make a simple definition of hue as the set of ratios R:G:B.
Suppose a colour (i.e., an RGB) is divided by 2.0, so that the RGB triple now has values 0.5 times its former values.
Explain using numerical values:
(a) If gamma-correction is not applied, does the second RGB have the same hue as the first RGB, when displayed? (we're not discussing any psychophyisical effects that change our perception - here we're just worried about the machine itself).
(b) State all colour triples for which the hue is unchanged.
