### Arguments

`col` | vector of any of the three kind of R colors, i.e., either a color name (an element of `colors`()), a hexadecimal string of the form "#rrggbb" or "#rrggbbaa", or an integer i meaning palette()[i]. Non-string values are coerced to integer.
`alpha` | logical value indicating whether alpha channel (opacity) values should be returned.

### Details

This is merely a wrapper to `col2rgb`, defined in order to follow this package's naming conventions.
