>Shops that didn't sell black doors would be losing business from non-superstitious people looking to buy black doors, which might be a bigger factor if superstitious group is relatively small.
It's not about selling, is about having black doors of your store. If 10% of the people absolutely refused to go through a black door (because of some BS religious reason for example), stores would either paint their black doors some other color, or lose 10% of potential customers. Guess what most will chose. The 90% of the people who are indifferent to door color wont make any difference.
