ocean: Oceanography perceptually uniform colormaps

Description

These palettes have been designed to be a collection of perceptually uniform colormaps designed for oceanographic data display.

Usage

ocean.algae(n)
ocean.deep(n)
ocean.dense(n)
ocean.gray(n)
ocean.haline(n)
ocean.ice(n)
ocean.matter(n)
ocean.oxy(n)
ocean.phase(n)
ocean.solar(n)
ocean.thermal(n)
ocean.turbid(n)
ocean.balance(n)
ocean.curl(n)
ocean.delta(n)
ocean.amp(n)
ocean.speed(n)
ocean.tempo(n)

Value

None

Arguments

n

Number of colors

Author

Palette colors by Kristen Thyng. R code by Kevin Wright

Details

The 'oxy' palette does not include gray as shown in Thyng (2016).

The 'balance', 'delta', and 'curl' palettes were originally given as 2*256 colors (256 each for the left and right half of the palette) and have been downsampled to 256 colors.

The palettes from matplotlib have been converted from RGB codes to hexadecimal strings for use in this package.
