Details
The function returns a color vector that starts with pure green, gradually turns into white and then to
red. The power gamma can be used to control the behaviour of the quarter- and three quarter-values
(between red and white, and white and green, respectively). Higher powers will make the mid-colors more
white, while lower powers will make the colors more saturated, respectively.
