To dye or not to dye? Quebec gets yellow margarine

There was a long-standing regulation in the Canadian province of Quebec prohibiting dairy manufacturers from adding yellow food coloring to margarine, meaning the butter-like spread came in it's natural form -- a so-called unappealing white substance. That is, until a few weeks ago. The regulation was recently lifted and Quebecois are now free to enjoy artificial coloring in their margarine, according to the National Post.

Is this a good thing? On one hand, their margarine looks like margarine does everywhere else in the world -- like butter. But I don't know how I feel about artificial colouring -- I think I'd prefer to see how my food really looks than have chemicals added to make it look good.

What do you think? Is artificial colouring in foods a yay or a nay?
