There are companies that actually dye your grass green in the US. Very handy if you are caught between a municipal law that forbids watering the lawn and a wacky HOA that DeMaNdS the lawn to be green, or else!
They don't beat them as such. The law only says that you are not allow to water your lawn. The HOA just fines you for letting the grass "deteriorate". They don't care about why it deteriorates, as long as they can fine you.
