I had a go at rebalancing the colour in the picture, but however much I got the red out of the background, the bass body stayed stubbornly red. Eventually everything else was blue, except the body. So I don't think it's a camera effect.
I was thinking of bidding on it, on the basis that I'd get it for the start price and that's ok for a G3 here. But my Rippers talked me out of it. Ended with no bids and not relisted so far.
