The WS2812 appears to be backwardly-compatible with the 400 KHz WS2811 signal. If you can precisely match the latter chip’s timing, either type will respond. '''The WS2811 protocol is not simply a half-speed WS2812'''. The duty cycle for the “0” and “1” bits is slightly different. From the [http://www.adafruit.com/datasheets/WS2811.pdf WS2811 datasheet]:
