Colour of water hose

I have a couple of white hoses for campground use. I fill my steel tank at home with whatever hose is on the outside valve. Typically, I'll run some water through the hose to eliminate that usual plastic taste. Actually, after I fill the steel tank with 20 gals of water, there is no taste of hose in the water. I bleach-rinse the system every year to remove any bacteria or algae/rust that inhabits the water system.

FWIW, I've had a drink from regular garden hoses in different locations for 60 years, never a problem.
