Inquiring minds want to know, Why is there a lime green splash on wall
Of the first stall in the front ladies bathroom?
It looks like someone used the wall to clean a wide paint brush
or is it a sign for zombies? or did someone think that lime and eggplant go together?
It’s called … Art! 
The British?
I thought it was the lime and the coconut that went together.
Your vision has misled you. That’s the result of a paint-peeler. I.e., someone who fidgets while they sit. They peeled the purple off of the green.
Thanks for the explanation
