Re: Is Jack Faragasso wrong about shadow behavior in colored light?

Sorry [b]theBongolian[b], but I don't see it as you do. If we are talking about the second pic, with the incandescent ambient light, the colour of the cast shadow must be from the ambient light. That shadow is burnt orange, close to that of an incandescent source. The complement of the green hue is magenta, but none of that is showing up.

You make an arguable point. But when I hold my color wheel up to the cup shadow displayed on the monitor I get an exact match on my color wheel to 30% magenta. There is a "back and forth" to be made about color accuracy of monitor/photo etc. but first I would ask you, rather than assign a name by eyeball (if that's what you did), - put a color wheel up to the cup shadow on your monitor and see what result you get.

Re: Is Jack Faragasso wrong about shadow behavior in colored light?

Okay - I realized by me holding a color wheel up to the monitor I was using an "eyeball" test - comparing the wheel against the cup shadow by eye. SO I loaded the cup in PS and used the color picker on the shadow area - and---
it turned out to be a burnt orange as oddman claimed. Now the color accuracy of the photo/monitor etc. can still be put into the mix -- but I think at this point the preponderance of evidence points to burnt orange.
