R: Create colors in a red-yellow-blue color scheme

oceColors9B {oce} | R Documentation

## Create colors in a red-yellow-blue color scheme

### Description

The results are similar to those of `oceColorsJet()`, but with white hues in the centre, rather than green ones. The scheme may be useful in displaying signed quantities, and thus is somewhat analogous to `oceColorsTwo()`, except that they (average) eye may be more able to distinguish colors with `oceColors9B`.

### Usage

    oceColors9B(n)

### Arguments

`n` | number of colors
