Above the Question grid, in the top right corner, you can open the Column panel used to select which columns to be displayed in the grid. The order of the columns can also be rearranged by drag and drop in the column panel.

When the column is visible, simply select a color by ticking in any of the square boxes and alter the color.  When you’re done changing the colors for your various questions make sure to click save at the top left of your screen.
