My hair changes color on it's own.

Not really but I really wish it did. That would be cool.

*nature *blues

They have an inherently superior material that can take away the overheating problem engineers face today at every aspect of miniaturization and you're presenting a technical difficulty to the manufacturing process...

From wikipedia:
Natural blue diamonds containing boron and synthetic diamonds doped with boron are p-type semiconductors. N-type diamond films are reproducibly synthesized by phosphorus doping during chemical vapor deposition. Diode p-n junctions and UV light emitting diodes (LEDs, at 235 nm) has been produced by sequential deposition of p-type (boron-doped) and n-type (phosphorus-doped) layers.
