it's possible to set a custom icon and color on a subflow?
I would mean, not the icons available with node-red, but something like a uploaded png file.
you can use any of the icons available - which include the font-awesome 4.7 set, or any icon included by another installed node. But apart from that no. And no you can't change the colour.
At some point in the (not immediate) future the idea is that the nodegen project will allow you to convert a subflow into an installable node - and at that point you would be able to fully customise it.
