Wind turbines are usually painted light-grey, with aviation safety lights at the top of the nacelle.
The tips of the blades are sometimes painted orange or red to improve daytime visibility of the
blade swept area while remaining unobtrusive to the character of the landscape as far as
practical.
Turbines are fixed to the ground and stabilised using
reinforced concrete platforms, which
ensure that the turbine remains stable. Foundation platforms are constructed below ground
level, and soil will be placed over the platform to return the visible area to nearly its original
condition.
