084 is just very weathered, looking back at the 141/181/071s they seemed to get different shades of orange depending when they were repainted, some got dayglow red panels and others did not. I haven't seen 084 in few weeks now since it came off the taras after having to rescue 086 which failed on another tara link.
Here is a photo I got of it back in May I think, at Clontarf Road.
