Thanks for the links, only the www.coloredburlap.com link doesn't work
(guess their site is temporarily unavailable?).

I think it was a joke. There is no "coloredburlap.com"
registered, at least not on *this* planet.

Polyether would be excellent, but while it IS possible to buy them in
all kind of nice bright colours, after about a year they have all
taken on the very same colour: grey. Please correct me if you have a
different experience.

Perhaps it depends on the quality, environment, (and color?)
