I think white cars are commonly preferred in hot climates, as there is a noticeable difference in the inside temperature of a white vs black that have both stood parked in the sun for most of the day.
You can usually get into a white or silver car and drive it away. With a black car, you may have to leave the doors open for a few minutes to allow the broiling-hot air to escape. Interior temperatures can easily reach the far side of 120F.
But white paint also withstands desert sun much better. Just a few years with a lot of outside exposure will make blues and greens in particular look sandblasted like they’ve been exposed to the weather forever
