I scanned the front cover of Seed of Light from my personal copy; the JPEG of the artist’s airbrushed artwork sans text is from Paul Hartzog’s Flickr photostream.

ABOVE: Edmund Cooper, Seed of Light (Kent: Coronet Books, 1977), with cover art by Jim Burns.
Not sure which of the two images above displays the correct colour, but at this moment, I think I prefer the one with the overall greenish cast and softer focus, i.e. the printed cover.
Finally, yes, the cover of my copy of Seed of Light has a wraparound image. But the fact is, earlier today, when I scanned the front, I simply was not in the mood to scan the spine and the back and piece it all together.
