Sorry, I don' see anything voorwerp or voorwerpjes like in this image. They have these very bright colors.
Did you check out the voorwerpjes thread in the old forum?

Voorwerps are usually a pure colour, since they absorb and re-emit light at only a few frequencies. This blue galaxy looks as if it has a range of colours. So I think a blue galaxy. A bit ghostly looking, maybe it has low surface brightness. However, the galaxies may be interacting, since both have a similar PhotoZ.
