if the cell in question is cell A1

use conditional formating, with the formula
=isblank(a1)=true and select red

copy this cell as required

Hi!

Assume the cell in question is A1.

Select cell A1
Goto Format>Conditional Formatting
Select from the drop down list: Formula is
Enter this formula in the box:

=A1=""

Click the Format button
Select the Pattern tab
Select the color of your choice
OK out

If the cell of interest is A1, click on cell A1. Then click on FORMAT, then
CONDITIONAL FORMATTING.
Set condition 1 to "formula is". Then in the formula field type
"=isblank(a1)". Then click on the format button and choose the format you
want (pattern .. red in this case).
