>>52581634Flames turn from orange/red to violet/blue the hotter and cleaner they burn. This is why a gas fire burns blue while a coal fire is red, why a blowtorch glows blue, and why the hottest stars are Blue Giants while the coolest stars are Red Dwarfs. The implication is that Ceruledge burns a lot hotter than Armarouge, which makes sense because it focuses its flames to form blades that cut like a blowtorch while Armarouge only launches fireballs from afar and doesn't need to 'cut' anything.
