Default [Q] LED colour when gets notification

Im just realise that on my whatsapp i set the colour of notification to yellow, then when i get new message, its not blinking yellow, only white colour (in STAMINA MODE)

then i try to turn off STAMINA MODE, it can blink yellow LED, so anyone know how to override the setting so that it can blink different colour in STAMINA MODE? i try to exclude from STAMINA MODE, but sadly it dont turn yellow. by the way, im using stock rom 4.3, fully root
