On the Subject of Graffiti Numbers
The answer to this puzzle is spray painted on the wall. Hurry up and punch it in!
 The module consists of a graffiti wall containing nine painted numbers from 1–9. Each digit will only appear once. Warning: '7' and '1' look similar.

To disarm the module, you must spray paint the correct buttons in the order dictated by the rules below:
 If there are more red numbers than green numbers, start at Rule #8 and progress in reverse order.
 Otherwise, if there are more blue numbers than yellow numbers, start at Rule #6.
 Otherwise, if there are more green numbers than blue numbers, start at Rule #4 and progress in reverse order.
 Otherwise, start at Rule #1.
 In each instance, if the rule is true, spray that number.
Rule #  Rule 

1  The left column is in ascending order (top to bottom). 
2  The top row is in descending order (left to right). 
3  The sum of the four corners is greater than the sum of the other numbers. 
4  The number '1' is blue. 
5  The top row is mostly primes. 
6  The last digit of the sum of the first two numbers in a column is equal to the bottom number of the same column. 
7  The sum of the two diagonals are not equal. 
8  The corner numbers have no more than two colours. 
9  Fewer than three rules are true (at this point in your calculation).
