Create Colors Similar to the Matlab Viridis Scheme

This is patterned on a matlab/python scheme that blends from yellow to blue in a way that is designed to reproduce well in black-and-white, and to be interpretable by those with certain forms of color blindness. See the references for notes about issues of colour blindness in computer graphics. An alternative to oceColorsViridis is provided in the viridis package, as illustrated in Example 2.

Usage

oceColorsViridis(n)

Arguments

n

number of colors to create.
