Dear community,

I am looking at options to install an external curtain in a big window door that gets lots of afternoon sun.

I keep reading contradictory information about which is the best colour for that: answers are either black/dark or white... I don't know what to make of this information. Is there a right answer here and, if yes, which?

Alternatively, would UV-blocking vinyl be a better option? (I have to take into account that I feel confident in my abilities to install the curtain, but not so much the vinyl.)

Thanks for your help, and stay safe out there in the heat.
