I recently re-watched guardians of the galaxy vol.2, and the creature at the beginning could shoot rainbow colored fire. This got me thinking, (as in my spare time sometimes I like to just write a world down. 'worldbuilding' I guess, I'm dumb) is there any way for a biological entity (plant, animal, bacteria, etc) to create a chemical that burns in all colors in the spectrum randomly/pseudo-randomly.
All colors not in a way that makes white, but it splits off in 'sparks' that glow individual colors. I'm hoping for the flame to look similarly in effect to thermite, where there is a main almost fluid flame and many sparks coming off.
Initially I researched this myself as I'm new here and kinda scared to ask in fear of looking stupid. I found what kind of elements burn what colors, like sodium burns orange, carbon/hydrogen burns blue and violet, copper makes green and lithium burns red. Other chemicals as well used in fireworks for example give more specific colors. But I don't know a way to combine these into a single compound/mixture that achieves the effect I want.
- What I want is a chemical that will burn with a similar effect to thermite, with a flame that glows randomly throughout the entire color spectrum, and produces sparks with random colors too (sparks optional)
- Amount of heat produced doesn't matter. It can be room-temp, burning or metal-melting temperatures I do not care
- This 'chemical x' must be able to be produced biologically. Preferably no handwavy methods like 'it just has this certain chemical on hand to produce it 24/7'
- Feel free to go as nit-picky as you want. If it includes something like quantum randomness that determines the energy of the photon released when the electron jumps to a lower level go ahead.
What is the chemical, how is it made, and what does it look like :) thanks
This is for an alien planet, mostly as decoration for the indigenous people there or some form of mating signal for fauna? idk anyway I'm off track. The life is carbon based with iron blood chemistry. There is about the same amount of resources on the planet as on Earth, however if something needs to be changed let me know. The atmosphere is Earth-like too but with more O2.
