So I have the Colour spectral breakdown of a number of stars (sdss data) and I was hoping there was a technique or process I can conduct/run in order to tell the actual appearance (as it might seem to someone viewing them), as it might seem to an observer? an example of one of the lines/observations is:
ra dec u g r I z
2.111125647 -0.935711213 22.04581 21.63591 21.73088 21.47245 21.43542.
Anybody who as any kind of experience dealing with this data, I'd be genuinely delighted to hear from, or in fact,
anybody who as any thoughts at all on it!
Thanks in advance,

I'm not sure you can?
Maybe, seems to be some conversions made?
The SDSS Data, processing the Data (http://cas.sdss.org/dr7/en/sdss/data/data.asp)
Photometric Flux Calibration (http://classic.sdss.org/dr7/algorithms/fluxcal.html)
And from that to Ugriz colors.
Potential colors for studying stellar
populations. (http://www.google.se/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&cad=rja&uact=8&ved=0ahUKEwiM7fOgxofQAhXGApoKHfHCBwsQFgg3MAI&url=http%3A%2F%2Fjournals.cambridge.org%2Farticle_S174392130700782X&usg=AFQjCNFXwWy31Amoa40sWNfRFNRwwAx0dg&bvm=bv.137132246,d.bGs)
Transformations between SDSS magnitudes and UBVRcIc (and ugriz ) (http://classic.sdss.org/dr7/algorithms/sdssUBVRITransform.html)

As for how a star looks to the naked eye?
White, yellow, red I'm not really sure what you're after here?
This? SDSS Filters (http://skyserver.sdss.org/dr1/en/proj/advanced/color/sdssfilters.asp)
Actually I think most stars would look 'white' to me, (except possibly red ones), in space outside a atmosphere? I'm not sure though?
