A moratorium is in effect on adding information from Fire and Blood until December 20th.
Dragonflame or dragonfire is the fire produced by a dragon. The dragon expels its fire from its gullet and out of its mouth. The older and larger the dragon the more devastating its fire. The High Valyrian word for dragonfire is dracarys.
Dragonflame can come in different colors. Where the flames of Balerion were as black as his scales, the flames of the dragon Sunfyre were golden, while the Blue Queen is known to have breathed flames in the colour cobalt.
Known dragon flames: 
- Drogon's flame - black fire shot with red
- Viserion's flame - pale gold shot through with red and orange
- Rhaegal's flame - orange-and-yellow fire shot through with veins of green
- Balerion's flame - as black as his scales
- Tessarion's flames - cobalt blue
- Sunfyre's flames - golden
