After you click on the cogs icon you will see a popup window appear (as shown below).
Click on the Background tab
Click on the drop down field Background Style, and choose the value Single Colour.
You will now see a colour selector tool appear, this tool will let you choose the colour you want to set as your background colour.
You can now choose to click on the colour palette to select a colour, or type (cut & paste if preferred) the hexadecimal (Hex) colour reference in the input field (as shown below the example of #1d1d1d).
Hex is a 6-digit, 24 bit, hexidecimal number that represents Red, Green, and Blue. An example of a Hex color representation is
12 is Red,
34 is Green, and
56 is Blue. There are 16 million possible colors.
After selecting your Hex Colour value, click on the Choose button to set this colour.
Finally, click on the Save button to save and close the popup window.
As shown in our example above you will see the background of the row set to the colour you have selected.
