bpy.colors {sp} | R Documentation |
Create a vector of `n' ``contiguous'' colors.
bpy.colors(n = 100, cutoff.tails = 0.1, alpha = 1.0)
n |
number of colors (>= 1) to be in the palette |
cutoff.tails |
tail fraction to be cut off on each side. If 0, this palette runs from black to white; by cutting off the tails, it runs from blue to yellow, which looks nicer. |
alpha |
numeric; alpha transparency, 0 is fully transparent, 1 is opaque. |
A character vector, `cv', of color names. This can be used either to create a user-defined color palette for subsequent graphics by `palette(cv)', a `col=' specification in graphics functions or in `par'.
This color map prints well on black-and-white printers.
