I think it's coming from the light source and not the onion. Try another object and see if the shadow is still yellow.

i had to go back to flickr to find some of the answers there:

erix! said: J.W. von Goethe has explained this in his "Farbenlehre", I'm definitely sure of that.

Try this experiment with apples of different colors, oranges, etc.

In a dim room (lights off) with a spotlight to shine on the fruit.
Put the fruit on a white background and shine the light so that it makes a shadow. A red apple will have a green(ish) shadow, a yellow apple will have a purple(ish) shadow. The shadows are in complimentary colors. It is not just a trick of the eye, because it shows up in photographs as in your picture of the onion.

I would love to read a technical explanation too.

the thing is that a shadow always is the complimentary colour of the original colour..
