Hi MRB,
As far as I know, using the one rule in the Conditional formatting, we can only format the cells with one color if the condition is true and if the same condition is false, the formatting of the cell will be blank and if both conditions are true, the formatting of cell depends on the highest ranking/priority of the rules in Conditional formatting.
Moreover, the formatting of cells in column B, C, etc., depends on whether the cell in the Column A starts with ABS, as per my knowledge, we need to applying conditional formatting for each row. Like this:
