Differences between the first state and second state may be the result of different expansions of the hose, different pressure pressures within the hose, differences in amount of fluid within the hose and different tensions states for the hose. Observed color changes between the first state and second state may be a color change, a color shade change, alternating rings of at least two different colors or shades of color along the length of the hose, a color pattern change or even the generation of indicia on the hose.
