- Green: 430C/806F
- Orange: 560C/1040F
- Red: 610C/1130F
Once they reach the specified temp range, they oxidize which turns them green/red: white or an orange/off-white (yellowish tint). If they reach the peak temperature.
Tech tip: disc paint should be painted liberally onto the entire width of the disc including vane and rotor cheeks.
