So I'm designing that world with several species that all go back to a single empire that after it's fall had things radically change for the whole world.
One of the things we all know and love about fiction is the crazy hair colors. While magic exists I'm loath to introduce it in this point and simply want the following.
An actual plausible, as in breaks no scientific laws but may not exist, medical condition that results in the humans of that race having their hair follow all our laws except it has crazy color like blue or green and has a sort of side effect.
The race are 100% humans but long ago they dwelled in a small country, think a small kingdom.
Now I'd love the side effect to be tied in with the color thing because I can just make it up and said: Because of the element hioglatrin in their food that resulted in their hair taking more exotic color but has the side effect of random pain attacks in their adults.
Just an example.
Anyway It there is a hard scientific limit to what the side effect is then great. If not then what is the most realistic side effect? If it does not matter then it is fine.
I know it sounds stupid but I know very little of biology and this is theoretical biology so that' pretty tough for me.
This hair condition and side effect, if any, can be the result of anything but here is a few ideas to make to more fitting to the world.
- A particular food in their original habitat.
- Exposure to magical powers that resulted in that condition overtime.
- An element in the water.
- An element in the air.
- A sort of disease that they developed immunity to after a while but not without side effect.
Honestly whatever you want. I just want a scientific solution.
