Get background colour of cell

Is there a method or property of a cell that will tell me what the current background colour of a particular cell is?

The background-color of cell may be defined in multiple ways , so it is not simple to detect the current color. Can be done through DOM methods as

var cell = grid.cells(i,j).cell;
var color = window.getComputedStyle?window.getComputedStyle(cell,null)[“backgroundColor”]:cell.currentStyle[“backgroundColor”];
