Conditional Formatting Based On Selected Values Of Two Dropdown Menus

I am building a spreadsheet with a column having two drop down menus at the top that designate independent, but strict conditions. For simplicity, say I have in cell A1 a drop down menu with choices "alpha, beta, gamma" while A2 has a drop down menu for "1, 2, 3". These six values sit off to the side in cells X1, X2, X3, X4, X5 and X6 respectively.

In cell A3 I woul like to change its color, perhaps to green because it is an acceptable number (say less than or equal to 100) or change to red if unacceptable, value greater than 100.

I can do both of these commands in Excel, no problem. In my situation, I would like to change the value at which cell A3 goes from green to red dependent on the options in A1 & A2. There are 9 such combinations of alpha, beta, gamma, paired with 1,2,3 and I would like the combinations to change the fill color of cell A3 in the following manner:

If A1 = alpha and A2 = 1, then A3 will be green for values less than or equal to 100 and red for values greater than 100.
If A1 = beta and A2 = 1, then A3 will be green for values less than or equal to 80 and red for values greater than 80.
If A1 = gamma and A2 = 1, then A3 will be green for values less than or equal to 60 and red for values greater than 60.
If A1 = alpha and A2 = 2, then A3 will be green for values less than or equal to 95 and red for values greater than 95.
If A1 = beta and A2 = 2, then A3 will be green for values less than or equal to 75 and red for values greater than 75.
If A1 = gamma and A2 = 2, then A3 will be green for values less than or equal to 55 and red for values greater than 55.
If A1 = alpha and A2 = 3, then A3 will be green for values less than or equal to 92 and red for values greater than 92.
If A1 = beta and A2 = 3, then A3 will be green for values less than or equal to 72 and red for values greater than 72.
If A1 = gamma and A2 = 3, then A3 will be green for values less than or equal to 52 and red for values greater than 52.

How to create a cell that can change its conditional formatting based on the selected values of two drop down menus.

I have a few other conditions I would like to implement, say change the fill color of A3 to green, orange or red dependant on the values in A1 & A2, but I might be able to crack that if I can see how the above scenario is done.
