I would like to know are there any (relatively) easy options to adjust color transparency (alpha value) in ArcMap (any version, any license)?
I think that's easy to do in ArcGIS Pro because, as you set a color (anywhere), you can adjust Alpha value.
The only option in ArcMap is layer transparency. That's not enough.
In example. I need plenty (say 10 of them) of road transparency options according to road category. I don't like to make loads of queried separate layers for all road categories as sometimes it get's too many values.
Same is needed with label transparency. I think it's impossible to set label transparency in ArcMap. Unless converting labels to annotation which is an uneasy & ugly idea.
I am not into programming and developing software.
