Generate a green-black-red color sequence of a given length.

Usage

greenBlackRed(n, gamma = 1)

Arguments

n

gamma

Details

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.

Value
