The point is to get all the colors green. the last one moves by itself so that's easy. The 1st and 2nd one move together, so I matched #3 and #4 together first. Then I used #3 to move the green #1 around randomly (up and sideways) until I could get it to match up with #2.
One: make #5 green
Two: make #3 & #4 green
Three: use #3 to match #1 to #2.
Four: align all the colors to green
I don't have a step by step, sorry. It took me about 20 minutes of fiddling with it to get them all to work together.
