I have loaded custom color palettes using company branded colors. The categorical palette defaults to 60% opacity in the marks card. I would like to set the default to 100% for these custom palettes so the colors render per brand standards. Alternatively, I would be happy setting the default opacity for all palettes in a workbook to 100%. Is this possible?
I don't know of a way to do it in the Preferences.tps file, but this method might work.
I'll bet you can set the opacity values once before you publish the workbook - that should stick when it gets to server.
