The idea of creating this color-picky doorbell is that I found that sometimes there are always people not wearing the correct color of clothes at parties or meetings, even when the dress code is announced. So, this picky doorbell will be a possible solution to prevent people from wearing the incorrect color of clothes because they will know the doorbell will never ring, and I will never come open the door for them unless they follow the dress code. The pun here is that the doorbell lights up with the sound of entering door codes when the dress"code" is correct.
