I want to resolve a problem of branding colors

In my NSIS I changed different colors, like the background of the branding text.

But I see that some times it appears in white like I asked its, and some times it appears in grey, like its defult color.

I absolutely not control that and it is very unpleasant.

Does anybody know how to resolve it ?

Thank you !

There are a few layers of controls there to make sure it looks right. So make sure you color them all.
