> In which case the color space you would work with would have "no emission" that's not at 0, accurately answering the original question. I don't expect a tech forum like this to be limited to the application layer.

That depends on whether your idea of pixels is as emitted by the application or as transmitted to the display.

Since the latter is hardly relevant to the majority of cases, I left it out. Maybe on simplistic platforms like Windows you'd have to care. But if you're a run-of-the-mill application developer making a game or web app or something... in no world do you have awareness of nor control over what's transmitted to the display.

So bringing up analog signals or OS-level color management as a 'gotcha' is being unnecessarily pedantic.
