Reliable Color Picker Across Windows & External Apps

  • Feature Request: Reliable Color Picker Across Windows & External Apps

    Right now in Affinity Photo 3, the Color Picker only works consistently inside a single document window. If I have two Affinity windows open, or if I try to sample from an external app like PurRef or even the desktop, the picker often reverts to white/black instead of grabbing the intended color.

    It would be a huge workflow improvement if the Color Picker could:

    • Sample colors reliably across multiple Affinity document windows.
    • Capture pixels from external apps (PurRef, browsers, desktop) when macOS screen recording permissions are enabled.
    • Clearly indicate which swatch (Primary vs Secondary) is active when sampling.

    This would make multi‑document and reference‑board workflows much smoother for digital artists, without needing screenshots or workarounds.
    Where do I post feature requests? I love this forum.

  • While the color picker tool has never been able to do this, the color picker within the Color panel can (and, to the best of my knowledge, has always been able to). See my attached video.

    Reverts to white. Same as the 2 dozen workarounds I tried, and 3/4 hour I spent with Copilot before it too decided outside color picking couldn't be done ' ). smadell appreciate the attempt. You're a good colleague.

    Actually, it can & does so in the same way as in V2, but it is not obvious. The trick is to first click & hold somewhere inside the document window. Then you can drag the tool into the desktop or any other window that is open & accessible.

    If you want to pick from a different open document in the app itself, you can't do that if they are in different tabs so you have to drag one out into a new window. A PITA but it works.

  • That method with dragging the picker is broken at least on Windows currently. The overlay is stuck, some can escape it with ESC; I for example can't, I can only force close the app from the outside.

    I mostly use the color picker from Windows PowerToys, it copies RGB hex by default, and then you can past the hex code in the RGB hex mode of the color picker in Affinity. Of course, when inside Affinity, I would prefer the internal color picker, as it uses the picked value directly.

    Likely it is a windows policy restriction.
    Rightclick the exe or the shortcut and click the "Run as Administrator"option (you only need to do this once)
    Use the pipette from the colors or swatches panel and not the "well" thingy or the alt+drag option as this will make the selector get stuck most of the time and you'll need to force close affinity.

  • Here's a portable color picker for windows
    Pipette

    Got one for Mac.
    Color picker drag from inside to outside doesn't work. That was among the 25 things I tried ; ) So happy, though, I posted a feature request

  • Color pickup using the pipette outside the Affinity workspace does not work for me either.

  • Color picker drag from inside to outside doesn't work.

    Are you certain that you are first clicking & holding the mouse button down somewhere inside the document window before dragging it out of there into some other part of your screen?

    Like I said, this works for me in both Affinity Photo V2 & in V3.

  • Color pickup using the pipette outside the Affinity workspace does not work for me either.

    It works for me, setting the third tiny color 'well' to the picked color. Have you authorized V3 to 'record' your screen in System Settings, which is the poorly labeled authorization needed to pick up colors from outside the app. (I has nothing to do with Affinity recording anything, since the app can't do that.)

  • Setting 'record' your screen in System Settings>privacy was one of the first of my many, many attempts. And I always click dragged dropper inside to outside.
    Years ago I tried to make this happen in v2, got most of the same suggestions in the old forum.
    It was interesting dealing with Ai. At first Copilot insisted it would work. But as I gave it feedback after each of my attempts, Copilot finally admitted it wouldn't work, "Affinity Photo 3’s Color Picker tool is really only reliable inside its own document window. Even with Global set and macOS permissions enabled, it doesn’t consistently grab pixels from external apps or the desktop. That’s why you keep seeing it revert to white/black when dragging outside — the tool isn’t designed for true system‑wide sampling."

  • Settin 'record' your screen in System Settings>privacy was one of the first of my 25 attempts. Years ago I tried this in v2. Curiously it worked 1 time then stopped. Never made it happen again.

    kath Are you certain you are holding down the mouse button when you click somewhere in the document window & then not releasing it until after you drag the pointer out of the document window & into some other item visible on your screen?

  • kath I realise this doesn't address the lack of functionality in the current version of Affinity, but depending on how important it is to your workflow, you might consider XScope. It's a power-house of tools that does a LOT more than just colour picking, so it might be overkill if that is your single purpose. Listed at USD 50/- for a license, but with a free trial so you can validate if it works for you.

  • I can definitely confirm that the V3 pipette doesn't work when dragged outside the app window;
    while it works perfectly under similar conditions in V2.6.5, at least on macOS 12.7.6.

  • The issue I am talking about, and that worked fine in V2:

    Windows

    The color picker where you drag from inside the color spot to any place on the screen inside or outside affinity and pick up the color when releasing. It shows the correct color and can be dragged anywhere, but releasing the mouse button does not close the overlay that is attached to the mouse pointer and also does not pick the color (it is not visible in the spot I have been dragging from after releasing the button). This overlay does not close with ESC either, and at that point I have to force close the app to get rid of it.

    I don't think it is a policy issue, that would be not very common in Windows. I tried opening affinity as admin and it did not change anything. Usually in Windows you do not need to set permissions explicitly for apps to "record the screen" and alike.

    The actual color picker tool from the toolbar however only picks up colors from the workspace/canvas and works fine.

  • Are you certain you are holding down the mouse button when you click somewhere in the document window & then not releasing it until after you drag the pointer out of the document window & into some other item visible on your screen?

    That's exactly how I do it. Affinity has the necessary access rights. It doesn't work for me with V2.6.5 either. No matter what I try.

    It isn’t better for me! It doesn’t display on my (old) iPad; I’m guessing that it’s in 4K.
