Reproducing this effect in layout

[PaulMcAlenan]

I was reminded of this:

The best Style achieved by accident

On the subject of achieving a SU Style. What I would like to define as a Style I can only achieve it when (in default Style) I click on an element within the composition and the rest of the comosition greys out. [Water%20Filled%20Barriers] Does any one know how I can achieve this look by editing a Style.

Does it help?

Looks like the OP got their effect using desaturated colours (?).

If you change the edge colour to a grey, your highlighted structure would also have the grey edge colour…
