问题
Right now I check if a cell is blank, if it is, it becomes red.
=ISBLANK($B$12)
However this cell only needs to be red when it's empty AND another condition is met: the cell above needs to be set to "YES" or blank.
I tried doing something like:
=ISBLANK($B$12),($B$11)=!"NO"
But that doesn't really work.

The AND function can combine the logic in the manner you are looking for. Try the following,
=AND(ISBLANK($B$12), NOT($B$11="NO"))
'or,
=AND($B$12="", $B$11<>"NO")
You will likely want to remove the $ absolute anchor from either the row or column if you want to apply that condition to more than a single cell.
These formulas are applied with the 'Use a formula to determine which cells to format' option. They are put into the 'Format values where this formula is true:' text box.

You could check for the cell being blank and above being "YES" with the following:
=AND(ISBLANK($B$12),EXACT($B$11, "YES"))
