Colour Confusion

Still coughing, still not going out.

But that means I can stay in and play with my Christmas present. It's a colorimeter, so I can set the colours and contrast on my monitor accurately. I think this blip of a photo of a blip shows the problem - each one has a different colour balance. Would they all come out the same if my monitor was set correctly, I wonder? Or is that expecting too much?

Happy Christmas to everyone on Blipfoto.
