It's painted of course, but it always seemed odd to me that the whole idea of a light woven hat was to keep your had cool, and

There isn’t a consensus that darker hats are actually warmer wearing. It sounds counterintuitive, and I personally believe they are slightly warmer, but the numbers suggest there is little if any difference.

A black object absorbs more incident radiation than a white object.

Whether this translates to an open weave hat being warmer, I’m not sure.

I'm not following why this is “counterintuitive”.

The darker brim will reflect less light from underneath which could add to the feeling of coolness. Is this the best of both worlds? I dunno -- but it feels cool enough that the hat requires a wool hatband.
