I'm actually kind of pleasantly surprised at the amount of design effort that went into "unmarketing" a product.
I didn't actually realize until the recent John Oliver clip that AU was the first country to introduce tobacco plain packaging laws. Reading up, I was amused by this unintentional offence to the olive industry:
"Government research found that olive green was the least attractive colour, particularly for young people. After concerns were expressed over the naming of the colour by the Australian Olive Association, the name was changed to drab dark brown."
