Color for automobile have codes , these codes are specific for a certain shade of color , if you go to any Sandox shop or any color shop they ask you the color of car and the code , they feed the code in the computer and the machine makes the same exact shade . so no more human errors .
For example Mazda RX-7 the color is Innocent Blue Mica and the code is 20P
For example VW Beetle the color is Bahama Blue and the code is L519
