[sumeetadur]

Add 5 pre-defined colours for the IC and FTA themes for charts with more than one data series.

This is the current colours object for FTA. Hex colour values can be added to the line, column and bar arrays:

// path: src\scripts\themes\fta-web.js
var colours = {
    line: [
        '#ff9246'
    ],
    column: [
        '#ff9246'
    ],
    bar: [
        '#ff9246'
    ],
    accent: '#ff9246'
};
