“…Any sort of glove is miserable at those temps, or even close to them. Sun screen is really the ticket here…”
It may seem counter intuitive at first, but at very high temps, some insulation can actually be helpful. This is partly because heat energy always flows from areas of higher energy (heat) to areas of less. A number of ancient desert dwellers often, for traditional garb, wore somewhat thick woolen robes–sometimes also very dark colors. This puzzled researchers, because again, it seems counter intuitive.
Researchers found that the insulation of the clothes helped to insulate them from the heat of the sun and surroundings while their sweat and the evaporation next to the skin, created a micro climate keeping them relatively comfortable. (Water is not only significantly more conductive than air, but water evaporating carries A LOT of heat energy with it. Evaporative, water based coolers in arid conditions can easily get 20 to 30 degrees below ambient temps.)
Or put it this way. Would you prefer to stick your hand in a hot oven bare or with some kind of insulation over it?  And, would you prefer to stick your bare hand in a regular oven vs a high convective “air fry” type oven (answer, definitely the former! because it will heat up less quickly). So when hot winds are blowing in an environ that is significantly above your core body temp, some insulation and wind blocking actually helps as long as your sweat is evaporating and creating that micro climate next to your skin. And if the clothes are thick and/or insulated enough, it doesn’t matter too much color it is or isn’t. (It very much does with thin, very breathable, less insulating clothes though).
Note, this does not apply when it is both very hot and humid, and thus sweat doesn’t evaporate efficiently. In the shade nekked and not moving much is the best you can do there.
