Colour coding is very common in automotive manufacturing. In most
instances, it is utilized for sorting purposes (i.e. sorting suspension
springs by spring rate) During a project at Ford's light truck assembly
plant in Louisville, Kentucky, I noticed no less than three bins of front
coil springs along side the chassis assembly line. Each box contained
springs that were painted with a particular colour stripe. The spring
supplier sampled each spring according to free length and rate and then
marked them with a corresponding colour. These colour coded parts enable
the line worker to quickly identify two like springs thereby avoiding
inevitable ride and handling faults.
