It reverts to a light blue color on the site, although it changed during bebuilder. I thought it might be related to cookies and tried a few browsers as well. Still same. It doesn't change. Why?
I found the cause of the problem. The first Flatbox does not have this part. That's why it's working properly. But there is such a place in Other flatbox. And no matter what color I do, the color here is valid. This must be a bug
You need only to remove the Deprecated color.
It is not a bug. You can read more about it here:
