Custom LED Color: Primarily, the Custom LED is there to know which Ember Mug belongs to who. We've seen that many people have multiple mugs in their household and being able to pick up the empty mug and or press the power button to see that it is their custom color helps our coffee/tea drinkers know which mug is theirs. It also allows the user to associate their specific temperature to their color, so they don't accidentally drink out of a mug that is not set to their perfect temperature. And lastly, it gives a personal touch to each mug and the owner using it.
Your personalized LED color will only show up when pressing the power button or if the mug is empty - giving the mug a little shake will illuminate your color as well!
