Syntax

map = abyss

Returns the colormap with as many rows as the current colormap.

map = abyss(m)

Returns an m-by-3 colormap.

Description

Each row is one color, ordered from the lowest to the highest data value. Apply the map with colormap(abyss(64)). All colors are blue-dominant, so it suits data where a dark-to-light progression is enough and warm hues would distract.

Input arguments

m: Number of colors. The default is the number of rows of the current colormap.

Output arguments

map: Matrix with m rows and three columns. Each row is an RGB triplet with values between 0 and 1.

Example

Four colors

c = abyss(4)
size(abyss)

Output

c = 4×3
