 Custom layer effects can be done by defining this in your `<keyboard>.c`:
 
     void rgb_matrix_indicators_kb(void) {
-        // rgb_matrix_set_color(index, red, green, blue);
+        rgb_matrix_set_color(index, red, green, blue);

 A similar function works in the keymap as `rgb_matrix_indicators_user`.
