At sundown, at that meadow, that's the color of Half Dome as the setting sun strikes it.
Good to see from Sentinal Bridge too at that hour.

Note that the rock next to it, not hit by the sun, is a natural color.

Other cameras had the same color results. And then we had a beautiful sunrise
the next morning as the sun rose over Half Dome and lit the meadow, at about 8:40am.
