My Sony TRV900 is a 3-chip camera and it registers 365nm UV as being a very rich green; my X5T UV thusly shows up as a kind of cyan color as the UV trips off the green sensor while the blue sensor picks up the actual blue. For the IR from remotes, the Sony shows a yellow color.
My single-chip Canon digicam, however, shows a more "realistic" purple color for the UV lights, and a rather desaturated purple for the remote.
I would expect that the representation of color from IR and UV sources is a rather unpredictable thing from manufacturer to manufacturer, as it depends on the response of visual filters in a "don't care" region. But then, if most CCD's come from a very few sources, it would be more consistent than that.
