Stuck in Salvation V.2 by Peppeyhare4000

I already gather that the houses are color coded to the numbers but that gives me red: 11; blue: 74; green: 124. and I know if I switch red first then red again - I get the affirmative sound. Also..switching red first and then switching blue I get the affirmative sound. and lastly red first and then purple (switch 4) I get the affirmative sound. But how do I get the green (switch 3) and what am I missing? lol
