In X4 you had the ability to create a color docker and when you wanted to change a color throughout the file you could drag new color over and replace it throughout the file. I never could find when I upgraded to X7 and now that I have upgraded to 2019 I thought I would look again. It was a great feature and I hate always having to back save and go to old computer to complete that task.
Color Styles?
Yes, color styles do it
I found the color styles. But I am not having luck dragging a different color over it and changing the color in the project.
