If I lived in one of those houses, would I be able to paint it whatever color I wanted (e.g. pink and yellow stripes)? Or is there some sort of coordination to make sure they all look appealing as a set?
You can choose whatever colour you want. It seems they used to me more sombre but around 50 years ago the owner of the hotel decided randomly to paint it bright yellow and neighbouring houses along the front thought it was a great idea and started choosing their own outlandish colours.
