The reason you use color coded hoses is to make them easier to tell apart. For instance; When a firefighter pulls a pre-connected hose off the engine and runs towards the fire, the pump operator is setting up the pump and may or may not notice where each hose is going so by color coding the hoses he is more aware of which hose is where on the scene. That way he is more likely to charge or discharge the right hose at the right time. Planning BEFORE the fire is very important.
