Forward voltagesAn interesting aspect of LEDs is that as their colour moves from red through the visible spectrum into blue, the voltage dropped across the LED increases with the decrease in wavelength. In other words, the forward voltage increases, or in the twisted, hilarious world that is electronics, the voltage might be considered to become more forward.

Rather like these three LEDs on a semi-conductor dating show.
