## Get distinct colors

### Description

Get a set of distinct colors selected from `colors`.

### Usage

    getDistinctColors(n, start.color = "blue4", exclude.colors = c("white",
      "black", "gray", "grey", "\\<yellow\\>", "yellow1", "lemonchiffon"),
      exclude.brightness.above = 1, exclude.rgb.above = 210)

### Arguments

`n` | Number of colors to select. If `n` is a character vector, `length(n)` will be taken as the number of colors and the colors will be named by `n`.
`start.color` | Color to start the selection process from.
`exclude.colors` | Character vector with colors that should not be used.
`exclude.brightness.above` | Exclude colors where the 'brightness' value in HSV space is above. This is useful to obtain a matt palette.
`exclude.rgb.above` | Exclude colors where all RGB values are above. This is useful to exclude whitish colors.

### Details

The function computes the euclidian distance between all `colors` and iteratively selects those that have the furthest closes distance to the set of already selected colors.

### Value

A character vector with colors.
