It would only appear as a coloured area if the rendering coloured it so. The standard Mapnik output only puts a name on boundaries (not sure if it even renders parish ones or not). There are no true area features in OSM, just a selection of polylines (Ways) that end to end create one. For things like boundaries some folks will group all the polyline items into a Relation so that they have a container to keep all the split sections in. This isn't vital though providing the boundary has the same tags on it all the way around. One benefit of a relation though is that you can reuse sections of boundary Way which are also part of some other boundary where they coincide. This removes the need to create ways on top of ways (shared nodes).
For colouring of areas for your own needs a purpose rendering would be needed. Hope this is helpful. Other may have further suggestions as there is no hard and fast method of achieving the same end.

These boundaries are polygons, yet the boundaries in OSM that I see are lines. >From some articles I have read, I assume that the OS boundaries are merged with the OSM Data Layer in JOSM and adjusted if necessary to join to existing boundaries or deleted where they are coincident, but they are not completely redrawn. How, then, is the apparent conversion from polygon to line achieved?" Frederik Ramm has replied, informing me to split ways. I had done that and although the ways are split, the polygon still appears to retain its qualities: moving the single way that was split still takes the adjacent ways with it, and selecting any of the other ways still highlights the polygon area. It does not revert to a series of lines, or polyline. Copying the selection to a new layer, the boundary retains its infill, so I would imagine that would display as a coloured area if it was uploaded to OSM. Is there something I am missing here?
