I work with color all day in my job to ( Automotive Painter ) and the numbers are called color codes for all cars , but I know GM colors so well after 30 years I just look at a car and know the Paint Manufacturers # but I dont see colors in numbers though .
Just 3800 is PPG's GM truck White , 4154 is PPG's Victory Red , ect...... thats how I see colors and numbers
