Hi Aram!
Now that's the best (and the only good) explanation for black robes
in the desert that I've seen!
Unfortunately, black also radiates the heat better, which is what
causes the M8's "magenta twist" - especially with synthetic fabrics.
Does your science wizardry extend to explaining why synthetic fabrics
would cause more problems than, say, cotton or wool?
Cheers!
