Volcano bursting fireworks

The yellow and green goes very well together, it even looks like a galaxy and the purple-blue is the star belt.

The red almost looks like hands, and the  green looks like spikes. It's like looking at a god. However, green and red do not go well together.

This looks like a fire and water angel, one half fire, the other water.

It's like looking at a volcano bursting out flames, lava and smoke. All inside a dark room, coloured paper and a torch. White and red makes things look very hot, brighter the white the better. 

We used a long shutter speed at 30.
