"It was already one in the morning; the rain pattered dismally against the panes, and my candle was nearly burnt out, when, by the glimmer of the half-extinguished light, I saw the dull yellow eye of the creature open . . ."
-Mary Shelley, Frankenstein
Whatever the LED color, good luck bringing your creature to life. I can't help your efforts at all, but I did get those cell phone charger thingies and will send you one if you PM me your address.
Good luck Dr. Frankenstein!
