    In case you are using Windows:
    It is just a guess but you might ran into a combination of two issues here.
    Root cause is the way Windows handles the display's ICC profiles,
    the other one is how Affinity "finds" those ICC profiles.
    In general APhoto and I think the other apps as well, color correct their screen output according to the ICC profile set in Windows for the specific display. When you move the APP or its document window from one display to the other Affinity is switching to the ICC profiles accordingly. This happens when you release the mouse. So your rectangle changes its color as intended.
    First potential issue:
    If you don't have a proper ICC profile for each display Affinity gets wrong information and displays "wrong" color.
    Second potential issue:
    Even if you have correct profiles Windows might fool you. The issue is, that in some cases Windows does a wrong identification of the displays. It happens to me especially with two monitors attached to a notebook. In that case I have three displays. All of them have a correct ICC profile. But sometimes Windows reads my main display as the notebook display and assigns the ICC profile of that one. Affinity is then color correcting with the wrong profile.
    Solution:
    Open "Color Management" in Windows (just type "color" in the search field - it will then offer the color management console).
    And now the complicated part:



    Once you have set everthing, Affinity should work as expected.
    But even the system panel might get messed up by Windows. Whenever I feel something is wrong with my colors, I check those profiles settings.
    Affinity limitation:
    The developers of most graphic software I use, have identified this Windows issue and implemented a feature to directly assing the profiles instead of reading the Windows Registry.
    Example Firefox:

    Affinity does not have this feature so checking the Windows Color Management is the way to go then.
    On the other hand Affinity has the profile switching feature which alot of other software does not have. E.g. Firefox can only correct with one ICC profile / display. If its window is on my BenQ, I get correct colors, but if I move it to the Huion they are a bit off because Firefox still uses the BenQ profile. In my case this is not a big issue because both displays are calibrated to match sRGB quite accurately. So, the final corrections in the profiles are not to much appart.
