Darlene,
many years ago, the Chinese did that [ with black umbrellas
------ maximum heat absorption
]
It has to be at least white
So your shade cloth is white ?
Never really gets that hot down here, umbrellas are for rain.
Most whites [ think UK white - pale and pasty ] down here go brown like the local white, Syrians / Italians
and that area go dark brown. Only the nose bridge indicates the race.
You can learn alot about how a person feels about their place in society.
Newcomer Chinese try to stay fair, but local Chinese born here could care less.
The fairness of UK skin is due ton their wheat diet, once down here, they revert to the colour of the
original race out of North Africa.
Back to heat absorption ---------- air temperatures --- as Grimmy stated.
Thanks a million Grimmy.
Good Day
Anthony
