colour-range

colourRange(range, options) ⇒ Array.<string>

Get as wide a list of unique colours as possible, based on shifting the hue of the colours

Samples from the 'colour wheel' at equally spaced intervals, where red (#ff0000 / rgb(255, 0, 0) / hsl(0, 1, 0.5)) is the starting point.

For example: calling colourRange(3) will give you 3 colours as wide apart as possible, in this case red, blue, and green [ 'ff0000', '00ff00', '0000ff' ]

This works for providing up to 360 unique colours

Kind: global function
Returns: Array.<string> - - List of unique hex values
