Light and ColourObjects do not have a colour; it is the light reflected from the object that is the colour we see.
The visible spectrum.

Linear and Log light perception
One Candle in a dark room...
Linear assumes that each candle contributes the same amount of light to the overall level that our eyes can see
Linear and Log light perception
In Log the apparent change in brightness between one candle and two is the same to our eyes as between two candles and four.
Linear and Log light perception
In linear each step in exposure is a uniform increment
In a log each step is larger than the previous one
[ie for each f-Stop up on a camera you double the amount of light] Linear Gamma Curve
Human eye = LogCelluloid Film = LogComputer Screen = LinearVideo camera sensor = Linear
Cameras apply a Gamma curve to the Linear information from the sensorComputer screens apply an inverse Gamma curve to interpret Log images on a linear display
Log images have a perceptually greater dynamic range by having slightly less range in the mid-tones and more levels of exposure in the shadows and highlights
