I suppose not. The translucent range circle I did on Coniosis is just a tag before the tools are created. You can, by the color section, apply opacity tho. CSS has a selector called rgba which allows you to apply opacity too, but isn't the same as the normal opacity, and that's a different matter (nothing mention-worthy).
