I am trying to find a way to have a cell in column A turn yellow if any cell in the adjacent row is less than the value of its corresponding header. Please see my

Then, for yellow you can use:

=COUNTIF(BYCOL($B5:$H5,LAMBDA(each,each<OFFSET(each,4-ROW(each),0))),TRUE)

It checks in each column if the value is smaller than in row 4, and counts the amount of TRUE values

And green should be by default, I understand. Is it useful?
