```c
rgblight_sethsv(HSV_WHITE, 0); // led 0
rgblight_sethsv(HSV_RED, 1); // led 1
rgblight_sethsv(HSV_GREEN, 2); // led 2
// The above functions automatically calls rgblight_set(), so there is no need to call it explicitly.
// Note that it is inefficient to call repeatedly.
If your keyboard lacks onboard underglow LEDs, you may often be able to solder on an RGB LED strip yourself. You will need to find an unused pin to wire to the data pin of your LED strip. Some keyboards may break out unused pins from the MCU to make soldering easier. The other two pins, VCC and GND, must also be connected to the appropriate power pins.
