Background mask does not change color

[Roel22315872jf2s]

When i select the background via the AI masking tool and then go to the color button to change the color of that background, i do not see anything happen on the background itself. I have no idea what's happening, my system requirements seem ok....

Anybody has a tip for this please?

is this a photoshop question?

Apologies, it is a Lightroom Classic question...

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

The color thing here does a multiply with the selected color. Unfortunately since your background is black (meaning zero in all channels), it has no effect. The color tone you are doing here only affects mid tones. What you want to do is raise the exposure of this background so it becomes grey and then you should be able to affect the color using this patch.

Adding color means adding an overlay. If you overlay color on top of black, then you will still have black. That means it is not possible to change a black background to color by using color overlay. What you can try is this. Use curves, and move up the lower left point of one (or two) of the three color curves. If you want a bright color, then also raise the exposure a bit. Your screenshot suggests you want to change the background to green, so move lower left point of the green curve upwards. I'm typing this on my iPad, so I can't show a screenshot from Lightroom Classic, but I mimicked it in Lightroom on my iPad.

Deleted, rethinking. Yep, my previous reply (deleted) was wrong, my bad.
