Color picker only returns white color despite sufficient privileges


Recommended Posts

Hi there

Does anybody know why the color picker in Affinity Photo 2.5.5 for macOS only returns white color despite Affinity Photo having sufficient privileges and, accordingly, being able to detect the correct color (as can be seen by the fact the picker's preview shows the correct color [see screenshots])?

 

Tested on macOS 14.6.1 as well as macOS 15.0 Beta(24A5331b).

Many thanks

Sebastian

What is your monitor setup, and what kind of computer do you have, @Sensational Sebastian?

Thanks for the reply. I am using a Mac mini 2020 16 GB running macOS 15.0 Beta(24A5331b)(to reiterate, this issue also occurred with macOS 14.6.1).

As for monitors, I am using two iMacs from 2010 in target display mode connected via miniDisplayPort.

Thanks. There is another report (which I will need to try to find again) about the color picker only picking white with an external monitor, which may be what you're experiencing.

Probably related to AF-504, but I was thinking specificly about this post in one of the threads with that Bug Tag:
