+### RGBW Support :id=rgbw-support
+
+Rendering the color white with RGB LEDs is typically inconsistent due to inherent variations between each individual LED die. However, some WS2812 variants (such as SK6812RGBW) also possess a white LED along with the red, green, and blue channels, which allows for a more accurate white to be displayed.
+
+QMK can automatically convert the RGB data to be sent to the LEDs to mix in the white channel:
+
+```
+w = min(r, g, b)
+r -= w
+g -= w
+b -= w
+```
+
+Thus, an RGB triplet of `255,255,255` will simply turn on the white LED fully (`0,0,0,255`).
+
+To enable RGBW conversion, add the following to your `config.h`:
+
+```c
+#define WS2812_RGBW
+```
+
## Driver Configuration :id=driver-configuration
Driver selection can be configured in `rules.mk` as `WS2812_DRIVER`, or in `info.json` as `ws2812.driver`. Valid values are `bitbang` (default), `i2c`, `spi`, `pwm`, `vendor`, or `custom`. See below for information on individual drivers.
