Will you settle for an orange car?? I've spent well over the alotted 5 minutes. Can't wait to see the solution to this one.

It really is a very fast solution....I have had frustrated students make the car plaid with a mask...
Think "Pin Grid" and see what you can do with that hint....Actually any color is possible for the car...

If you want to keep the lawn correct you cannot allow any change to the Green side of the A channel.
