Thanks Patrick and Harm for the suggestions! These could work as workarounds, but still not exactly what I'm after. I'm looking for a color that has an opacity / transparency channel, and this channel could be set between 0% (fully transparent) and 100% (fully opaque).
If that's not possible, maybe a work around could be to import a pre made graphic that was already semi-opaque.
