Photography is painting with light but this shadow saga is
getting really confusing for somebody like me that doesn’t know too much about
modern vapour lights.
I did some searching on the Net and discovered that the lower blue
spotlight is most likely mercury vapour light and the orange street light above
it is sodium vapour light. OK, not much to it, except: that blue
light casts orange shadow and orange light casts blue shadow! I will have to communicate
with somebody that designs street lighting to find out why the colors are
reversed.
You can see from this projection that higher orange street light’s
shadow is in front and blue spotlight’s shadow is in back…
…yet the shadow colors are reversed! Why?!?

Might start by checking “Subtractive colors” on the web…
Exactly what my artistic wife said :).Still, why would subtractive color apply to metal vapour lights?
