Plenty of old brochures for sale on ebay - if you go into a dealer and ask nicely though they may have an old brochure stashed that they could let you have.

There was a facelift in 2009, and the colours may have changed, I don't think by much. I bought my first Octavia new in 2009 - that was Race Blue but you had to have the vRS for that and the yellow.

Post-facelift there have been quite a few pale metallic colours, including pale blue and pale green which are quite pleasant.
