Mask Color Bug: Brush and Fill Color in Mask not Working, Only Black

There is a clear bug in the mask behaviour in the new 28.0.0 update. Mostly, painting in a mask only applies black, even when white is selected as the foreground colour. The brush is set to normal blending mode. Making a selection and filling it with the white foreground colour also fills the selection with black. The correct behaviour works for a while, but then the wrong behaviour comes back. Here is a video showing the error:

I just download PS V28, and this was the first thing that I found out. Painting (Dodging and Buring) on masks is one of the most basic and fundimental processes Photoshop can offer photographers. It is a technique that is founded from darkroom printing from film days. How on earth can this not be checked before the main update is released.

This is the pupose of having a Beta program, so bugs like this are picked up before they are released… but even further to that, checks should be made before the version is released to users.

Found one quick fix: making a selection in the mask and filling it with the foreground and background colour sometimes fixes the bug, but only until it appears again.

Definitely not a real fix, though.

Thanks for sharing the workaround, and I'm sorry that you're still experiencing this behavior.

Could you try disabling the option to 'Enable modern color User Interface' by going to Preferences, then Interface?

Once done, relaunch the app and check if it makes a difference,


Thanks,
Nikunj

OK, I could reproduce it again. Here is a video. I’m sorry for the length, but you can clearly see that in the beginning everything works as expected, and then suddenly after 0:31 second it stops working and paints with only one of the colours, no matter which one is selected. Keep a closer look at the foreground/background colour switch. Hope that helps.

It just happened again! But it was gone by the time I wanted to document it. It’s the same as in the initial video.

I had just started adjusting my settings to match my workflow. I switch off a lot of the default settings, like auto-select, show layer bounds on hover, etc. I’m also using the modern colour interface.

Here are some screenshots of my settings. Maybe that helps?

Hi, thanks for reaching out!

Like Dave, I'm not able to see the behavior on macOS 27.0.1. If you haven't tried any troubleshooting already, you can try resetting the preferences of Photoshop using the steps mentioned here: https://adobe.ly/48ttUpf

Please backup your settings prior to resetting the preferences. You can check: https://adobe.ly/4j7jKAy


If you continue to experience the same behavior, please share the System info as Dave requested.


Let us know how it goes!

Thanks,
Nikunj

I’ve not been able to reproduce this in v28.0 on Windows 11. What troubleshooting steps have you taken so far (e.g. resetting preferences). 
Can you post your system info from Help>System info.Copy

​@davescm & ​@nik.m 

Thank you for your quick reply.

I reset the prefs and am testing further. There is still something wrong, because was using the same settings as on earlier versions and never had an issue like this. Since the prefs reset, no issues yet.

Here is my system info:
