My hoses are that horrible blue colour. However they were cheap and it was only an experiment to see if the in-hose thermostat would work. I couldn't find black silicone hose at a sensible price and I was not optimistic so did it as cheaply as possible. It actually works very well so . . . it's still working 6 years on and if it ain't broke . . .
