Reported by Leandro in bug 134408

The Transparency field was added in 7.0 and it probably behaved like this from the start - didn't bibisect. I checked with linux-64-7.0 repository.

Comment 6 Miklos Vajna 2023-09-04 06:35:33 UTC

SvxColorItem has a single mColor to decide the color. Either it's COL_AUTO and then you get automatic color, or it's an actual RGBA color. In that case the alpha part of the RGBA can contain the transparency. So we currently don't have a way to represent "auto + x% transparency", but if wanted, probably it could be added with an explicit "auto" flag that is not part of the color value.
