Red was the colour of blood.

Red was the colour of fire.

The colonel remembered his time as major. His time as soldier, as human weapon in the Ishvalan War of Extermination.

He remembered the countless times he snapped his fingers, creating big, red flames that burned his enemies down to ash.

These times were dark, with smoke in the sky and blood on his hands. Roy's thoughts back then were filled with black emptiness, depression and pity. Pity for himself and for the people he killed.

He felt lost, lost in this nightmare. Everywhere was death and blood and fire. Whether it was his fire or the gunshots, whether it was the blood of his own men or of his enemies, death visited everyone. His scythe was red from the liquid, that kept the humans once alive.

But that wasn't the only time Roy was met with fire and blood. No, it continued, stayed by his side for all his life. Death was a part of life after all.

His sensei died, vomiting blood. The ishvalans died, bleeding out or being burned to ash. Hughes died, stabbed and shot, sitting in a pile of his own blood. The homunculus Lust died, burning in his red flames, feeling his anger and determination.

Fire and Blood, his life sinking in red death. Red gets black and flames die down, the blood flow stops and you meet your end. A cruel, but true cycle.

Red was the colour of his coat.

Red was the colour of his lips.

Roy smiled at the thought of the boy with the red coat. First met when his fire was almost completely vanished, he gave the boy new hope. Ed got his determination back, a new fire pushing him forward, a new goal that he wanted to reach.

When the colonel saw the blonde in front of the East City Headquarters, he couldn't help himself but smile. Edward chose the colour for his coat because of the blood he shared, the blood he gave for his mother, the blood for his brother. Even though Edward hadn't as much blood as Roy on his hands, for a young boy it's enough to change his life.

After he knew Ed better, the blonde explained, why else he chose to make his coat blood-red. Red looks good on him, the kid said smiling, and Roy couldn't help himself but admit it was true.

But soon Roy's eyes went from the coat to Eds face to his lips. Pinkish red lips parted softly as the boy smiled or were wide open when he talked. His tongue was nearly the same colour, just a bit darker.

Roy leaned towards the small alchemist, who still tried to explain the reasons why he made his coat red, but stopped talking when the colonel's lips met Edward's. Not only were his lips beautiful red, but sweet and soft too, so the black-haired man enjoyed the kiss to its fullest. Edward starred wide-eyed at him, until he closed his golden orbs like the black-eyed alchemist already did.

After some time, it could have been seconds, minutes or hours, Mustang didn't care, the two parted away and looked at each other. Red, there was the colour again, visible on both their cheeks as they heavily blushed.

Red was the colour of love.

Red was the colour of the heart.
