While there are workarounds for selecting and applying a colour from
the image, adding this option will significantly save time and effort.

Here is a bugzilla link which describes it in detail:

https://bugzilla.gnome.org/show_bug.cgi?id=470761 [1]

While I understand what you are asking for, I'm wondering why it is really necessary. The 2 options already exist: picking using the color picker tool or using the color dock.

These are 2 conceptually close yet different (and explicitly different even!) features. I don't think that we would really make a service to people by blurring this difference with more hidden options. When you use the color picker from the dock, you know you get a color anywhere from the *screen*, which are colors you don't necessarily have original values anyway, you get what is displayed. Having an option which would optionally grab from actually opened image in canvas would not only make the code complicated, it would also make the feature conceptually complicated (basically the feature works differently depending on where your pointer is standing). Whereas right now, it is simple: you have 2 different color pickers which work in 2 different ways. So depending on what you want, you use one or the other.

That's my initial reaction, though I can still change it.
I also understand that you may not want to care about the difference. From a simple point of view, they both pick colors, what is the difference? Who even cares about this difference? I get this. Yet the difference exists, we didn't invent it and I'm not sure if trying to blur this difference is not an actual disservice to people.


Except that the color picking from the 'Colors' dock is, on Windows,
limited to the Gimp windows (canvas and dialogs) or perhaps to the
windows using the GTK library. But you can't color-pick anywhere on
the screen like you can do in Linux.

Really? That sucks.
I am assuming it should be possible to color-pick everywhere on Windows too, no? So that's mostly an implementation problem/bug.
Patches welcome. :-)
