Cuba has a bewildering range of licence-plate (chapa) colors.
There is logic to each and every one, as each depicts a different usage.
Here's how to read them:
Black: foreign diplomatic corp
Blue: a state-owned vehicle for commerical use, such as a taxi or tractor
Brown: lower rank government official
Green (dark): Army
Green (light): Ministry of the Interior. You don't want to mess with this!
Maroon: Rental car
Orange (dark): Foreign business or journalist
Orange (light): Cuban business manager and officials
Red (dark): A company car that can be driven 24/7
Red (light): A company car that can be driven only during business hours
White: High-ranking government official. Don't mess with this either!
Yellow: Private vehicle

Moskvitch (Russian: Москвич) was an automobile brand from Russia produced by AZLK from 1945 to 1991 and by OAO Moskvitch from 1991 to 2002. OAO Moskvitch was a privatized venture name given to the former factory in order to avoid legal issues after the fall of the Soviet Union in 1991. The word moskvitch (Russian: москвич) itself translates as "(a) Muscovite" into English. It was used to point out the original location of the cars manufactured outside of Moscow.
