What are the meanings of the license plate black and white blue and yellow?

Friend who bought a special car for the first time must not understand what the black, yellow and blue colors of the license plate mean. I recently asked a friend who understands a special car and learned that:

Small-sized civilian cars have a green license and white letters. Public security special vehicles, licenses are white, red "ga", black characters. Armed police special vehicle, license plate is white, red "wj"; car, license plate is white, red Chinese characters: "A, B, C ..." black characters; embassy foreign car, license plate is black, white and hollow "Use" word sign. Consulates foreign cars, licenses for the ink, white and hollow "collar" sign; other foreign cars, licenses are black on white. Learning license plates are blue on a white background, with the word "learning" in front of the figures. Temporary licences are red on white, with "provisional" before the numbers; The car makes up the license plate and is black on white. The vehicle "movement certificate" is a yellow-red car on a white background (black and black lines on a yellow background) a blue car on a blue background (white line on a blue-white line). Yellow car: B can drive a blue car as above: C Driving; Yellow card vehicle charges are high; Blue card vehicle charges are low; Yellow card vehicle: You must go through a permit to enter the city; Blue card cars: You can enter the city;
