Also, don’t let the color of the background material in the first pic fool you. I realize it’s not easy for most folk to ‘see’ all this.
Regardless of all that mumbo jumbo, a thought experiment: how many Ed Whites (or 105.012/145.012s) have green lume today?
I have not seen one. It is highly unlikely that lume would start green and turn yellow/mustard, or vice versa, or any other color for that matter. Makes more sense that the base color remains in pristine unpatinated watches, and goes darker as it patinates or absorbs moisture (black spots?). Occam’s razor and all that. My milage clearly varies.
