This function creates a character vector of the colors used by the VMD molecular graphics program.

vmd_colors(n=33, picker=FALSE, ...)

## Arguments

n The number of desired colors chosen in sequence from the VMD color palette (>=1) Logical, if TRUE a color wheel plot will be produced to aid with color choice. Extra arguments passed to the rgb function, including alpha transparency.

## Details

The function uses the underlying 33 RGB color codes from VMD, See http://www.ks.uiuc.edu/Research/vmd/. Note that colors will be recycled if “n” > 33 with a warning issued. When ‘picker’ is set to “TRUE” a color wheel of the requested colors will be plotted to the currently active device.

## Value

Returns a character vector with color names.
