Confirming the problem. I got the desired result by correcting the source code, but I don't think I did it in a good way.

First on line 18466 I add j argument to sending object:

this.barHelpers.barBackground({
          bc: bc,
          i: i,
          j: j,
          x1: barXPosition,
          x2: barWidth,
          elSeries: elSeries
        });

And then on line 6180 I changed

if (bc >= this.barCtx.barOptions.colors.backgroundBarColors.length) {
    bc = 0;
}
var bcolor = this.barCtx.barOptions.colors.backgroundBarColors[bc];

to

if (j >= this.barCtx.barOptions.colors.backgroundBarColors.length) {
    j -= this.barCtx.barOptions.colors.backgroundBarColors.length;
}
var bcolor = this.barCtx.barOptions.colors.backgroundBarColors[j];

But it's actual for stacked column charts. Another type of bar-charts need changes in another places.

@densevoid Thanks for the hint. I tried your code and it worked fine.
Will fix it soon.
