When first launching the Model 3, Tesla only made a black color option standard and everything cost a $1,000 or more premium. Later, Tesla also eliminated some other paint options to increase production efficiency.
With so few colors and only black being included, it resulted in many Tesla vehicles being black as the automaker ramped up production.
After a few years of black being the only standard Tesla paint color, Tesla changed it to white in 2019. It has now been years of white Tesla vehicles, but Tesla finally changed it today.
Tesla updated its online configurator for Model 3 and Model Y to make Midnight Silver the standard color. For Model S and Model X, Tesla appears to be keeping white as the standard color for now.
