Add a "style" role column to the DataTable, specifying a color string for
each candlestick you want to change the color of::
var dataTable = google.visualization.arrayToDataTable([
['day', 'low', 'open', 'close', 'high', {type: 'string', role:
'style'}],
['Mon', 20, 28, 38, 45, null],
['Tue', 31, 38, 55, 66, '#FF0000'],
['Wed', 50, 55, 77, 80, null],
['Thu', 77, 77, 66, 50, null],
['Fri', 68, 66, 22, 15, null]
]);
