How much is battery life effected (if at all) by dark watch fact vs light watch face?

As I was scrolling through the different watch faces available on the Instinct Solar, I got to wondering if there's any battery life difference between using a watch face that's light in color (black numbers) or a dark mode watch face (with light numbers)?

I'd think that the dark mode watch faces would use more energy since the watch is using power to turn on the pixels (turning them black).

Anyone know?

No difference. Only changes of the state consume power. The static screen does not consume practically any current, regardless of the pattern displayed.

I am not sure I understand the question, but as I wrote, any pixel of the display draws some noticeable current only for the swapping of its state, not for the static state (regardless whether black or white). And of course, it does not matter where the pixel is, so there is no reason it should be different with the HR graph.
