Conditional formatting

[LORA255]

Hello everybody and thank you that you are here to help!

I need to make conditional formatting with three different colors to a single cell, but the rules for the three colors are not understandable and easy as a formula.

For example: 

Change the color of the cell C1 to GREEN (in the same time C1=A1*B1) if

A1=1 and B1= 1 or 2 or 3 or 4 or 5;

 or A1 = 2 and B1= 1 or 2 or 3 or 4

or A1=3 and B1 = 3;  

Change the color of the cell C1 to YELLOW (in the same time C1=A1*B1) if

A1 =2 AND B1=5; or A1= 3 and B1=2 or 3 or 4;

A1=4 And B1=1 or 2;

A1= 5 and B1 = 1;

Change the color of the cell C1 to RED (in the same time C1=A1*B1) if

A1 =3 AND B1=5;

A1=4 And B1=3 or 4; or 5;

A1= 5 and B1 = 2 or 3 or 4 or 5;

Please help me :)

Since you have not inserted an Excel file (without sensitive data) where you can explain your plans in detail.
I am sending you this information.
I will not create a file, because that is what it comes down to, the person seeking help should be able to do this in advance.
I can well imagine that you have an unsupported problem in front of you and are urgently looking for a solution.

But I cannot imagine that the person looking for help would like everything to be finished.

Because then it would be no help search.

For the GREEN rule it could be

=($A1=1)*( ($C1=1)+($C1=2)+($C1=3)+($C1=4)+($C1=5) ) + ($A1=2)*( ($C1=2)+($C1=4)+($C1=6)+($C1=8) ) + ($A1=3)*($C1=9)

and similar for other rules
