blue

And the colour of fire is yellow. Yellow and white and sparks flying.

Drawn as angry red and orange and yellow flames consuming a house in a child's drawing.

But you can see blue in fire if you look.

Blue fire. Blue flame. Blue heat. Blue desire.

The blue steals up your spine and shivers into your brain. Even if you are standing ten feet apart. Even if you are on another continent.

Blue is a hot colour.
