1000°c seems accurate:

Fun little science fact: Heated objects glow the same colors no matter what they are made of. It's called Black Body Radiation. The color chart shows what temperatures correspond with various "colors" of glow.

Heated objects glow the same colors no matter what they are made of

True only if light emissions aren't dominated by chemical effects or filtered by structural effects. Plenty of materials burn at different colors. Although if you wait out the chemical reactions and keep it heated, it does eventually end up with just blackbody radiation too 🤷
