Layer RGB feature is not working

[parasbhanot]

Hi everyone i am trying to change the colour of neopixel led strip when certain layer is switched but colour never changes to blue or yellow or while as per the documentation. it is stuck with red colour which refuses to change .

i have modified the code as per the layer documentation for rgb leds as given below :

import board

        elif layer == 1:
            self.set_hsv_fill(170, self.sat_default, self.val_default) # blue
        elif layer == 2:

        elif layer == 4:

Am i doing something wrong ?

[parasbhanot]

i have put debug statement everywhere and go the following serial logs

Code stopped by auto-reload. Reloading soon.
soft reboot

Auto-reload is on. Simply save files over USB to run them or enter REPL to disable.

If you don't have an active animation you have to apply the color change manually by calling the rgb extension's show() method.
