Instantiate a Rainbow, e.g.
Rainbow rb0 = new Rainbow(); //[0,100],red-yellow-green-blue Rainbow rb1 = new Rainbow(minNum:-10, maxNum: 10); Rainbow rb2 = new Rainbow.fromArray(['red', 'FFFFFF', '#00ff00']); Rainbow rb3 = new Rainbow.fromArray(['red', 'blue'], minNum: -0.5, maxNum: 0.5);
To interpolate a color among the spectrum, use the list access operator, e.g.
Rainbow rb0 = new Rainbow(minNum:-10, maxNum: 10); var myColdColor = rb0[-9.32]; var myWarmCOlor = rb0[8.44];
