I don't know the relationship Phoenix has with the supplier of their awnings, but somehow the awnings are color-coordinated with the color of the PC. Nobody ever talks about it, not Phoenix to us, and not us to Phoenix. It's one of those magical things that happens behind the scenes.
I don't know about the material choices, I never gave it a thought that there would be choices to consider.
Speaking about awnings in-general....When rolling up your awning, always make sure it has no leaves or sticks on it.
Trying my best closing a cleaned-off awning during a crazy wind & rain storm, a few wet leaves were blown back on and stuck to it. The next day I opened the awning to find that the leaves stained the awning. When we got home, I bleached and scrubbed, but those leaf outlines are there to stay. So now I have the "autumn" theme printed on my gray striped awning.
Does anyone here have a method in removing leaf stains from the awning?
