You can specify the colors by their name or by RGB or RGBA color classification. The RGBA classification stands for Red, Green, Blue and Alpha (opacity) and the values can range from 0 to 255.
For example, you can enter Sky Blue, R105 G5 B105, or R105 G5 B105 A135.
The color names that you can use in the worksheet can be found in the color palette.
Move the cursor over the colors and the color name
is displayed at the top of the color palette.
