splayed window casing

[Anonymous]

Hello,
does anyone know a smart way to model a window like this ?
I mean I’m interested in casing that is splayed only at one side and I’d like to be able to change its colour separately

Thanks

The Reveal options of Windows usually offer a Splayed Reveal. See attached image.
That vertical board: I would model that separately using the Morph tool.
