1. I entered the settings menu 2. I got to changing the color of the grid 3. I changed the color from black to green (as it always was) 4. I clicked ok 5. The color has not changed
Adobe After Effects version number - 25.0
Operating system - os 14.5 3.3 mac pro GHz 12-Core Intel Xeon W
Expected result - That color will change after changing the settings
Thanks for reporting it. Same problem on my end as well. We've filed a ticket. For now, you can reset the After Effects preferences to change the color back to the default.
I installed the new apps and in After Effects v25 the new 'change colour of grid' feature doesn't work for me. It's stuck as 'black lines', which obviously can't be seen on black or very dark backgrounds.
I use these grids all the time, so I'm hoping the fix is in the next update 🙏
Apologies for this issue. It is fixed in the 25.1 Beta builds and we are working on a 25.0.1 to fix this (and a couple of other issues) which we hope to have released next week.
