It sounds like yours is more severe than mine.

Yeah, I don't do much UI work any more, but when I do, I always try to 
make things as garish as possible to ensure that product management 
gives the colour selection a sober second thought before we release. :)

There was a period about ten years ago when I was working on 
colour-correction software. I always had trouble really understanding 
the use cases -- it was just a mathematical exercise for me.

I see that with red and blue, especially on monitors. It produces a kind 
of 3d effect for me, where it seems like one of the colours is slightly 
behind the other.
