To do so,
remove the current colors in your cells, then
select your range of cells (for example, A2:G50).
Open the Conditional Formatting dialog and
select the option to use a formula.
Enter the following formula, then set the color you want (e.g. Blue) for the alternating rows.
=MOD(ROW(),2)=0
If you wanted to assign a *yellow* background to the alternating cells (as opposed to the default no-fill background), you could
create a second condition using the formula:
=MOD(ROW(),2)=1
and choose *yellow* as the background fill color. This would create alternating Blue and *Yellow* rows.
