The quickest way to change the font color in multiple, randomly located cells in a worksheet is to first select or highlight the rows or columns that you want to change the font color. You can hold the ctrl key while select multiple cells. After, selecting you can now change the font color of everything you selected.
Click the Font Color icon on the Formatting toolbar to change the font color of one cell, copy it with the Format Painter, and then paste it into each of the other cells.
