ColorScheme

Parse a string containing coloring information and store it in an object.

Example:

let cs = new ColorScheme('10:red');

The important parts of the returned object will look like this:

{ 
  colorsText: '10:red',
  colorsJson: { '': { '10': 'red' } },
  range: [ 'white', 'steelblue' ],
  domain: [ Infinity, -Infinity ] }
}

Another exmaple using continuous colors:

let cs = new ColorScheme('1:0.7 2:0.8');

Yields...

{ 
  colorsText: '1:0.7 2:0.8',
  colorsJson: { '': { '1': 0.7, '2': 0.8 } },
  range: [ 'white', 'steelblue' ],
  domain: [ 0.7, 0.8] }
}

Apply colors only to molecules with a particular name:

let cs = new ColorScheme('>blah\n 7:orange');

...

{ 
  colorsText: '>blah\n 7:orange',
  colorsJson: { '': {} 'blah': { '7': orange} },
  range: [ 'white', 'steelblue' ],
  domain: [ Infinity, -Infinity] }
}

Specify a domain and a range for continuous values:

let cs = new ColorScheme('domain=0:10 range=red:green 1: 0.7 2:0.8');

...

{ 
  colorsText: '1:0.7 2:0.8',
  colorsJson: { '': { '1': 0.7, '2': 0.8 }},
  range: [ 'red', 'green' ],
  domain: [ '0', '10'] }
}

Other examples:

let cs = new ColorScheme('1-3:red 4,5:blue');
