Green-black-red color sequence
Generate a green-black-red color sequence of a given length.
greenBlackRed(n, gamma = 1)
n |
number of colors to be returned |
gamma |
color correction power |
The function returns a color vector that starts with pure green, gradually turns into black and then to
red. The power gamma can be used to control the behaviour of the quarter- and three quarter-values
(between green and black, and black and red, respectively). Higher powers will make the mid-colors more
green and red, respectively.
A vector of colors of length n.
