bpy.colors

0th

Percentile

blue-pink-yellow color scheme, which also prints well on black/white printers

Create a vector of `n' ``contiguous'' colors.

Keywords
color
Usage
bpy.colors(n = 100, cutoff.tails = 0.1, alpha = 1.0)
Arguments
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.

Value

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'.

Note

This color map prints well on black-and-white printers.
