Just to add. You can drag the colour of choice over the ungrouped elements either one at a time or shift click to select more than one. Also when you drag the colour over the element there might be a couple of states depending on whether it is a gradient fill; drag the colour to the top to change the top part of the gradient fill, to the bottom to change the bottom part of the gradient fill or the middle for a flat fill (when you drag the colour over the element you will see the drag icon change if a gradient fill is applied).
