To use this page, click on a set of buttons in the table below to define a region of keys you want to share a common color, and then add the ranges to as line in your led_instruction_t set in keymap.c.
QMK uses a bitmask to define subsets of keys to apply RGB effects to. An example of this

The below example will set your home keys (ASDFJKL;) to be green:
{.flags = LED_FLAG_MATCH_LAYER | LED_FLAG_MATCH_ID | LED_FLAG_USE_RGB, .layer = 0, .id0 = 2147483648, .id1 = 487, .r = 0, .g = 255, .b = 0},
