Change selection color on view-based NSTableView

Question

Standard highlighting color in OS X applications is blue.

Is it possible to change it to another color, e.g. gray?

Note that I am using the new view-based

Okay, So I do know that it already has an accepted answer, but for anyone like me working with an NSOutlineView and has .selectionHighlightStyle = .sourceList can use this code to make the selection grey. This method will not flicker when changing the selection and will also stay grey if the app is minimised.

NSTableView/NSOutlineView Delegate:

func outlineView(_ outlineView: NSOutlineView, rowViewForItem item: Any) -> NSTableRowView?
{
     let row : CustomRowView = CustomRowView.init()
     row.identifier = "row"

     return row
}

And then create a new CustomRowView.swift file with this:

class CustomRowView : NSTableRowView
{
    override var isEmphasized: Bool {
        get { return self.isEmphasized }
        set(isEmp) { self.isEmphasized = false }
    }
}

This will keep the selection grey at all times.
