If you have been sitting wondering how some people have the colour variants that you really want in Animal Crossing: New Horizons, while you are stuck with that eye-sore of a BRIGHT RED vending machine, then it might tickle you, or really upset you, that everything seems to be connected to the colour of the roof of the Dodo Airlines airport. Yep, blame everything on Orville and Wilbur.
Over on reddit, user PraiseHolo has been piecing together which colour leads to what and it looks pretty much like the theory fits. If you have a blue airport roof, you will get a green lampost and a grey vending machine.
PraiseHolo did a bit of groundwork to check on this, including several game resets. “After many resets and playing the starting quest about 8 times (up until the upgraded resident services so I could check the streetlamp colour), I realized I was only getting green streetlamps, and after some more resets I noticed that also happened with other furniture in the Nook Stop as well, such as the teacup ride.”
Well now you know… and now you know to ask your friends what colour roof their airport has so that you can work on getting your dream colours.
